  1. v0.2.0TouchVink v0.2.0Latest1 file

    First release with MIDI, the OLED screen and the interactive web manual.

    Untested on hardware. It compiles and the web manual has been checked in the browser, but this build has not been run on a Simple Touch yet. The bring-up checklist is in docs/PLAN.md.

    Flash

    Download TouchVink-v0.2.0.bin, put the Seed in DFU mode (hold BOOT, tap RESET) and flash it at flash.daisy.audio. It fits the Seed's internal flash, so no bootloader is needed.

    What's new

    • USB MIDI, both ways. ch 1 notes set the osc pitch and excite the loop. ch 10 notes 36–47 play pads P0–P11. CC 20–27 control S30–S37, and the pot takes over again once turned through the MIDI value. CC 28–34 set the switches, pad mode, attack, decay, steering and distortion. What you do on the panel is sent out the same way. Full map: webmanual/README.md.
    • OLED screen (optional). A 128×32 SSD1306 on D11/D12: boot animation, names each control with its value, progress bars for held gestures, and a status row.
    • Interactive web manual: jonwaterschoot.github.io/TouchVink. It works on its own, or connects over USB MIDI (Chrome/Edge) to mirror and play the device.
    • Switches match the panel: SW1 is the left lever (osc motion, LFO / steady / drunk, left to right), SW2 the right lever (noise, pink / drift / brown, top to bottom).
