Specifically, the instructions are for the assembly of kits v2 (version 2), those using the All-In-One circuit and the PiScreen 3.5' display. If you have an older kit v1, based in the 2in1 circuit and the PiTFT 2.8' display, you better should read [[Building a Zynthian Box using an official Kit | this tutorial]].

The Zynthian Software stack consist of:

−

+ '''GNU Linux Operating System:''' Raspbian Jessie (Minibian is used in the ~~last~~ SD images)

+

+ '''GNU Linux Operating System:''' Raspbian Jessie (Minibian is used in the most recent SD images)

+ '''Jack Audio Daemon'''

+ '''MOD-HOST + MOD-UI''' software, from [http://moddevices.com ModDevices] ([https://github.com/moddevices github repositories])

Line 43: Line 45:

The easiest way of getting the software is downloading the last ''official'' SD image from here:

−

'''[~~http~~://zynthian.org/~~download/zynthian_gorgona_omega_rbpi3_kitv2~~-~~2018~~-04-03.zip~~.torrent~~ Download Zynthian "~~Gorgona Omega~~" SD-image~~, configured for Kits v2~~]'''

+

'''[https://os.zynthian.org/2019-06-26-zynthianos-stretch-lite-1.0.0-RC3.zip Download Zynthian "Aruk RC-3" SD-image]'''

It's a 8GB compressed image file (plenty of soundfonts) compiled for Raspberry Pi 3. (Please, keep feeding the torrent after downloading!)

===Building the MIDI-IN/OUT/THRU connectors===

−

Before mounting the MIDI-IN/OUT/THRU connectors into the case we will solder the needed wires. Doing it in that way is rather more comfortable than trying to solder inside the case with all the wiring mess.

+

Before mounting the MIDI-IN/OUT/THRU connectors into the case we will solder the needed wires that allow connecting it to the All-In-One circuit using a JST connector. Doing it in that way is rather more comfortable than trying to solder inside the case with all the wiring mess.

'''JST Connector wires'''[[File:Midiconnfront.jpg|340px|right]]

−

~~If you want, you can protect the contacts using heat-shrink sleeve~~ (~~the~~ red ~~sleeve pieces in the photo~~)~~. In that case, remember to insert the sleeve pieces before soldering ;-~~)

+

* JST White (1) => LED's Anode (LED's red wire/long lead)

+

* JST Yellow (2) => LED's Cathode (LED's black wire/short lead)

+

* JST Black (3) => pin 5 of MIDI connector

+

* JST Red (4) => pin 4 of MIDI connector

−

~~[[File:IMG_4777~~.~~JPG|600px]]~~

+

If you want (i strongly recommend you do it!), you can protect the contacts using heat-shrink sleeve (the red sleeve pieces in the photo). In that case, remember to insert the sleeve pieces before soldering ;-)

+

===Mount the MIDI activity LEDS===

+

Insert the 3 LEDS in the case holes. You may want to push the LEDs with something more rigid than your finger. The screwdriver's handle could be fine.

+

[[File:IMG_2223.JPG|600px]]

+

[[File:IMG_2224.JPG|600px]]

+

When it's done, you have to solder the 2 LED wires (red/black) with the 2 spare wires on the MIDI JST harness (white/yellow). Polarity is important, so don't cross the wires:

+

* JST White wire (1) => LED's Anode (LED's red wire/long lead)

+

* JST Yellow wire (2) => LED's Cathode (LED's black wire/short lead)

+

After soldering all the 3 LEDs, you may want to protect the connection with heat shrink sleeve, adhesive tape or hot melt glue.

[[File:IMG_1401.JPG|600px]]

+

===Insert the knobs===

+

You should insert the knobs into the encoders before closing the case. This will avoid forcing the encoders too much as otherwise, you could break them. Follow these simple steps and you wouldn't have any problem:

+

* moisten with water or saliva the encoder stem and the knob hole

+

* press the encoder PCB with the finger from the rear side while pushing the knob from the front side until is completely inserted

The new Zynthian Kit 2 is designed to use JST connectors, so connecting everything is really straight-forward:

−

* Connect the Main Ribbon Bus cable to the RBPi's 40-pin header and also to the All-In-One module

{{NoteBox|At this point, if you have a v2+ kit (HifiBerry DAc+ADC soundcard with audio input), you should take a look to the [http://wiki.zynthian.org/index.php/Building_a_Zynthian_Box_using_an_official_Kit_v3#Connect_the_Audio_Jack_connectors v3 kit instructions].}}

===Connect the Display===

Line 400: Line 447:

It's easy to make a mistake while assembling the parts or connecting the wires. Some errors can be dangerous for the electronic components (short-circuits, some specific bad-wiring combinations) so it's better to be sure that everything is correctly assembled and connected.

+

Put special attention to ribbon bus connection and verify that red wire is on pin 1 for every connector. Also put attention to audio jack connectors and check that they are correctly connected to the Hifiberry soundcard.

===First Boot===

−

When you are ~~pretty~~ sure that everything is in its place, it's time to boot ~~by first time~~, so:

When you are sure that everything is in its place, it's time to boot the machine, so:

−

1. Insert the SD-card with the zynthian image ready to run. If you don't have one yet, [[#Zynthian_Software|read this]].

1. Insert the SD-card with the zynthian image ready to run. If you don't have one yet, [[#Zynthian_Software|read this]]. You can insert the SD-card through the "window" on the bottom-side of the case. Also, if the case is still open, you can do it from the top.

−

2. Plug the mini-usb power ~~conector~~. A good 5V micro-usb charger is recommended (> 2 Amp).

~~If you are using a SD image pre-configured for the Zynthian Kits v2, these~~ are the stages that you should see while booting:

+

These are the stages that you should see while booting:

−

1~~. Initially, the display must go white~~

+

1. After 5-10 seconds, it will show the Zynthian splash screen

−

2. After 5-10 seconds, it will show the Zynthian splash screen

+

2. After 3-4 seconds, it will go black

−

3. After 1-2 seconds, it will go black

+

3. If you are using a fresh zynthian image and it's the first boot, the stages 1 and 2 will be repeated

−

4. If you are using a fresh zynthian image and it's the first boot, the stages 2 ~~and 3~~ will be repeated

+

4. After 5-10 seconds, the zynthian UI will be shown

If you don't get an error screen or a blank screen, bad luck! Probably you made some mistake during the mounting process. You have to [[#Locating_and_Solving_problems|locate and solve the problem(s)]].

+

If you are using the Aruk RC-3 SD image (you should!), you are lucky because this SD image is pre-configured for working with the kit v2. If not, perhaps you need to configure the software for working with the kit v2. The simplest way of doing it is using the webconf tool:

−

If ~~not~~, ~~bad luck! Probably~~ you ~~made some mistake during~~ the ~~mounting process~~. You ~~have~~ to ~~[[#Locating_and_Solving_problems|locate~~ and ~~solve~~ the ~~problem~~(s)]].

+

* Connect your zynthian to your local network using an ethernet cable (RJ-45).

+

* From your web browser, access the zynthian's webconf tool by typing "zynthian.local" in the address bar. If this doesn't work for you, you should try with the IP. You can get the IP of your zynthian by navigating to the Admin Menu and clicking "Network Info". You should do that by using the "touch" interface: Click the top bar with a stick (or your nail, if it's not too wide) until you are in the Admin Menu. Once you are there, go down and click "Network Info".

+

* Type the password (''raspberry'') for login into the webconf tool.

+

* Once you are logged in, you have to access Hardware->Kit and select "Kit V2".

+

* Save the changes and reboot your Zynthian.

−

If you are using ~~an older~~ SD image that is not pre-configure for the Kit v2, then you ~~should configure~~ your ~~Zynthian Box's~~ hardware ~~using the [[Configuration_Users_Guide|webconf tool]]~~. These are the adjustments you have to do:

+

If you are using a really old SD image (you shouldn't!) that is not pre-configure for the Kit v2, then you have to specify every part of your hardware configuration. These are the adjustments you have to set:

* '''Display:''' PiScreen 3.5 (v2)

−

* '''Audio:''' HifiBerry DAC+

+

* '''Audio:''' HifiBerry DAC+ / HifiBerry DAC+ADC

−

* '''Wiring:''' ~~MCP23017_ENCODERS~~

+

* '''Wiring:''' MCP23017_EXTRA

* '''Style:''' FontSize = 14

===Test the Controllers===

+

===Test the Controllers & UI===

+

If you get into the Zynthian UI, then you should be in the 'Layer list' screen. Let's start testing that your controllers are working OK.

+

1. Rotate the SELECT controller up & down for selecting the different options in the Layers menu.

+

2. Push SELECT to create a New 'Synth Layer'. You should get into the 'Engine Selection' screen.

+

[[File:IMG_2496.JPG|600px]]

+

If it doesn't works, try rotating/pushing the 'learn/snapshot' controller. Perhaps you have cross-wired the 3 & 4 controllers and in that case, you have to fix the wiring. If it doesn't work, try pushing the other two controllers and rotating the controllers. If something happens, most probably you have reversed the wiring order when connecting the controllers. Double-check the wiring again.

+

3. Rotate the SELECT controller to choose the engine you want to instance for the new layer.

+

The selector must go down when rotating clockwise and go up when rotating counter-clockwise. If the rotation sense is reversed, you should check the wiring. Perhaps some harness is faulty. The wires color sequence should be: red, black, yellow, green.

−

~~If you get into~~ the ~~Zynthian UI~~, ~~then you should be in the~~ '~~Layer Selection~~' ~~screen. Let~~'~~s start testing that your controllers are working OK~~.

+

4. Select the ZynAddSubFX engine, select channel #1, bank 'Collection' and preset 'Metal Drips'.

−

~~1. Push 'select' to create a new layer. You should get into the 'Engine Selection' screen~~.

+

[[File:IMG_2497.JPG|600px]]

−

~~[[File:IMG_1563~~.~~JPG|600px]]~~

+

You should get into the 'Instrument Control' screen.

−

If it doesn't works, try pushing the 'snapshot' controller. Perhaps you have cross-wired the 3 & 4 controllers and in that case, you have to fix the wiring. If it doesn't work, try pushing the other two controllers and rotating the controllers. If something happens, most probably you have reversed the wiring order when connecting the controllers. Double-check the wiring again.

+

[[File:IMG_2500.JPG|600px]]

−

2. Rotate ~~the 'SELECT' controller to select the engine you want~~ to ~~start for~~ the ~~new layer~~.

+

5. Rotate every control to test that it works and that the rotation sense is correct.

−

~~The selector must go down when rotating clockwise and go up when rotating counterclockwise.~~ If ~~the rotation sense is reversed~~, ~~you should~~ check the wiring.

+

If some controller doesn't work correctly, check the wiring again. You could try to figure what is happening by analyzing the observed behaviour.

−

3. ~~Select~~ the ~~ZynAddSubFX engine,~~ select ~~channel #1, bank and preset. You should get into~~ the ~~'Instrument Control' screen~~.

+

6. Push SELECT to move to the next controller screen. Bold push to select a controller screen from the list.

−

~~[[File:IMG_1568~~.~~JPG|600px]]~~

+

7. Push BACK. You should go back to the 'Preset Selection' screen.

−

~~4. Rotate every control to test that it works and that the rotation sense is correct~~.

8. Push BACK again. You should go back to the 'Bank Selection' screen.

−

~~5. Push 'BACK'. You should go back to the 'Preset Selection' screen~~.

+

[[File:IMG_2498.JPG|600px]]

−

6. Push ~~'Layer'~~ again to return to the 'Layer Selection' screen. Try to create another layer following the same procedure.

+

9. Push LAYER again to return to the 'Layer Selection' screen. Try to create another layer following the same procedure.

−

[[File:IMG_2509.JPG|600px]]

−

7. ~~From the "Instrument Control" screen, push~~ '~~Snapshot~~' to get into the '~~Load~~ Snapshot' screen. ~~Push~~ 'Snapshot' ~~again to 'Save Snapshot'. Push 'BACK' to return to the 'Instrument Control' screen~~.

+

10. Push 'SNAPSHOT' to get into the 'Snapshot' screen. Select 'New Snapshot' and your first snapshot will be stored.

−

If everything is working OK, then you should read the [[Zynthian_Users_Guide|User's Guide]] and start enjoying your Zynthian Box, but before that ...

+

[[File:IMG_2506.JPG|600px]]

+

If everything is working OK, then you should read the [[Zynthian_Users_Guide|User's Guide]] and start enjoying your Zynthian Box, but before that ... why not enjoying a little bit? Connect your MIDI keyboard, your speakers and check this out:

+

Bank 'net-wisdom', Preset 'Vangelis Saw - C'

+

Keep pushing a single note (or a chord) and move the cutoff and resonance controllers. Enjoy! ;-)

===Test the Audio Output===

Line 474: Line 550:

1. Connect the audio output (RCA or Jack connector) to your amplifier or auto-amplified speakers.

−

2. Boot your Zynthian, select FluidSynth engine, channel #1 and '~~FluidR3 GM~~' bank. Select some instrument.

+

2. Boot your Zynthian, select FluidSynth engine, channel #1 and 'TimGM6mb' bank. Select some instrument, like "Piano 1".

3. You could add more layers for completing the band ;-)

3. Push BACK, holding the switch pushed more than 2 seconds. You should get into the 'Admin' screen.

~~When~~ everything is ~~working OK~~, it's time to close the case~~, but first~~ ...

+

Once everything is in its place and you have tested that it works, it's time to close the case ...

===Close the case===

=Update your Zynthian Box=

Line 518: Line 598:

If you are using the official Zynthian SD Image, the first thing you should do after booting up your Zynthian Box and having the controllers working OK is update the software:

−

- connect ~~the~~ Zynthian Box to your router using ~~a RJ45~~ cable

+

- connect your Zynthian Box to your router using an ethernet cable

−

- '''update ~~zynthian~~ software''' ~~from the admin menu~~

+

- from the admin menu, click '''update software'''

−

- ~~'''update zynthian library'''~~ from the admin menu

+

- from the admin menu, click '''restart UI''' (or '''reboot''')

−

- '''restart ~~GUI~~''' (or '''reboot''') ~~from the admin menu~~

The update process can take some time. Be patient. If you get some ERROR message while updating, please, [https://discourse.zynthian.org/t/problems-updating-the-software-from-the-admin-menu/386 ask in the forum]. You can send a photo or description of the error message.

+

You can also update the software using the webconf tool, or from the command line.

=Locating and Solving problems=

Line 529: Line 610:

In this section i will try to give you some tips for locating and solving the problems you may have.

−

For finding and solving problems, i really recommend to connect a HDMI display to the RBPi. It will give you accurate information during the booting sequence. Also, if you connect a USB keyboard, you ~~can~~ login into the system and get extra information, inspect the logs, etc.

For finding and solving problems, i really recommend to connect a HDMI display to the RBPi. It will give you accurate information during the booting sequence. Also, if you connect an USB keyboard, you could login into the system and get extra information, inspect the logs, etc.

−

===The display don't ~~go white in~~ the boot ~~stage 1~~===

+

===The display don't show the zynthian splash screen on boot===

−

~~I recommend you disconnect~~ the ~~controller and 2in1 modules and~~ try to ~~boot again~~.

+

In that case, probably the system is not booting correctly. You could try to connect a HDMI display and see if the system is booting. If you can't see the booting sequence, then you should re-burn your SD-card with the Zynthian image. Also, check that your image file is correct by using the SHA1 signature.

−

If ~~the problem persist it's very probable~~ you ~~haven~~'t ~~solder correctly~~ the ~~side 26~~-~~pin connector~~. ~~You should double~~ check the ~~connector and be sure that it's correctly soldered~~.

−

===~~The display don't show~~ the zynthian ~~splash~~ screen in the ~~boot stage 2~~===

+

===You get the zynthian error screen with the IP===

−

~~In that case, probably the system is not booting correctly~~. You ~~could try to connect a HDMI display~~ and ~~see if the system is booting~~. ~~If you can~~'t ~~see the booting sequence, then you should re-burn your SD-card with the Zynthian image. Also, check that your image file is correct by using the SHA1 signature.~~

+

Your hardware seems to be incorrectly configured. You should access the webconf tool and configure your hardware.

+

===Your controllers doesn't work===

−

~~'''More coming soon~~ ..~~.'''~~

+

You make a mistake while connecting the controllers or your hardware (wiring layout) is incorrectly configured. You should access the webconf tool and configure your hardware.
