Running minidexed on a touchscreen #697
-
Hi all, pretty new to this. A lifelong musician and fan of the various DX’s. I’d love to have one but could never afford to buy a real DX. But of course Minidexed looks like the answer to that particular dilemma. I have a PI m3 a waveshape 3.2 touch screen and a sub sound module and I’m wondering if it’s possible to get minidexed up and running in this setup and if so how. |

It isn't possible to run MiniDexed and make use of the touchscreen as the UI itself. If it is a HDMI touchscreen then it can be used as the debug console, but that is all I'm afraid. I don't know what a sub sound module is, but if you have a link I'll take a look. Note: this needs a genuine Raspberry Pi, so if by Pi M3 you mean a Banana Pi m3, then the answer is definitely no I'm afraid. Assuming a genuine Pi, then 0ne other option might be to consider Zynthian. I''ve used a Waveshare 4" HDMI touchscreen with Zynthian, but this is a full synth-oriented OS installation. It includes a number of Synth engines, including the fuller Dexed on which MiniDexed is based. Zynthian is quite a bit more resource intensive than MiniDexed though, so it might be ok for just Dexed on a Pi 3, but ideally a Pi 4 would be better. I have some details for Zynthian here: https://diyelectromusic.com/2022/06/30/zynthian-revisited/ Another, non-Pi option might be MicroDexed touch, but this runs on a Teensy 4.1 with a TFT touch screen - but that is a completely different project of course to your Pi 3 and a Waveshare (I assume its Waveshare not Waveshape) screen :) A different synth project that can use a HDMI screen is Rene's original minisynth project for circle. This is using the same bare metal environment as MiniDexed but for a pseudo analog-synth type device. See: https://github.com/rsta2/minisynth. My own notes about getting it running can be found here: https://diyelectromusic.com/2022/03/20/bare-metal-raspberry-pi-synth-part-4/ But yes, these are all for a genuine Pi (or Teensy in the case of MicroDexed). (If you are using a Banana Pi, I don't know if Dexed itself is available for the Banana Pi linux version you're using, but it might be worth a look...) Kevin |
