MicroDexed (Capacitive) Touch
THIS IS THE MOST RECENT VERSION
DESCRIPTION:
DIY Groovebox / Synth / Sequencer with 2x16 voices 6 OP FM, 16x voices MDAepiano, 2xVA, 2x16 MIDI Channels, 8 voices Chromatic Sampe Player/Pitched Drum Samples and 8x voices Braids Oscillator (shared with sampe player voices), based on a Teensy 4.1 in a tiny box.
Microdexed-touch required a Teensy 4.1, PCM5102 Audio Board, 320x240 ILI9341 SPI Display with Capacitive Touchscreen and a serial Flash Chip on a prebuild module. This helps to reduces the required soldering skills to a minimum.
Enhancements to prior version:
- Capacitive touch display (works similar good as your current smartphone touch)
- Easy Access: PROGRAM Button (mainly useful for development)
- Soft Power on/off (aimed at users building their own power/battery solution)
- Option for Headphone amplifier (has known issues but previous output is still available and is at the same quality as before)
- Digital output S/PDIF TOSLINK is now enabled by default and will give the best, possible sound quality output
What i can expect to receive when ordering PCB+ASSEMBLY instead of the pcb, only ?

MicroDexed started as a Teensy based, 6-operator-FM-synthesizer. The first generation is still maintained at: https://codeberg.org/dcoredump/MicroDexed
Compared to the previous Version, there are a lot of new features/improvements:
- The Flash Chip is presoldered on a small PCB attachment for <2$. You do not have to solder small SMD parts to add this to your build.
- "Large" Graphical Interface, view and edit multiple Parameters in one Screen
- Use external MIDI gear over USB or Mini TRS Jacks (DIN MIDI with adaptor) from 2 x 16 MIDI Channels in the Sequencer
- Map MIDI CC to external MIDI Devices to control Input/Parameters
- Global plate reverb, 2 global delay effects (500ms, with added PSRAM chip 60 seconds or even more)
- Loading, playing and editing multi-sampled instruments or layered instruments in a "live" mode or played by the sequencer. Auto detection sample zones but also can be edited manually. This is early work in progress and currently not stable when using pitch shifting and polyphony
- 2 instances of "Virtual Analog" Monosynths with one OSC, PWM, Multimode Filter and Noise. A lot of useful new sound possibilities.
- 8 voice polyphonic Oscillator, based on the code of Mutable Instruments - Braids. No wavetables but added individual envelopes and multimode filters for all voices
- Much improved Sequencer with 8 Tracks, 16 Step Patterns, 16 Step Pattern Chains, up to 16384 Song Steps, Arpeggiator with 1/8 - 1/64 Steps, Arp Patterns including Euclidean settings, Pitched Drum- and Instrument Sample playback
- The sequencer can also play chords of various types, stacked up to 7 notes, using only a single sequencer track
- Global Mixer View with all Channels
- Multiband Master Compressor with 4 bands
- Sample Management from SD-CARD and SPI FLASH, samples can be loaded/modified from SD-CARD to FLASH during runtime.
- Touch Mute Matrix for live / realtime performance
- Tracker View (Editor) - work in progress
- Track Print/Recording - work in progress
- Remote control in web-based 1:1 UI with added features (filemanager,filetransfer, screenshots etc.) Work in progress - connected to PC via Teensy MicroUSB Connector
Demo Reel/Usage/Feature Videos:
Virtual Keyboard much improved for drum sample input to sequencer
