In addition to: Own Fork - Where to start?
I am experimenting with a kind of headless Zynthian. Currently it is more a headless MOD-UI and not really working. The goal is to have a synth which only has some options to recall preconfigured setups for using it on stage.
Since the Zynthian GUI seems to work with a touchscreen this can also be done with a Zynthian and (engine-)presets. But on the Maker-Faires they ask us how to build a Zynthian without soldering.
I am currently also testing the integration of Pianoteq. I made am image with some GUI around for easy configuring: https://gigamove.rz.rwth-aachen.de/d/id/pMSoy2duNdNMjv (available until 13.2.2018). This one is working with a screen attached to HDMI and different soundcards (including HDMI audio out, so you only need a Raspi, a TV and a USB-MIDI-keyboard).
I ordered a HDMI-to-RSA converter to test if this is working replacement for a soundcard. So my easiest setup for a Zynthian (not really headless) is:
- Waveshare 10" HDMI capacitive touch display
- HDMI-to-RSA (between RPi-HDMI-output and Waveshare HDMI input)
=> no soldering. Costs about 170 EUR without keyboard. But you have to live with a touch interface for Zynthian.
As I wrote: It is more a kind of test than a real project.
