MicroDexed-touch
This is MicroDexed with TFT Touch Display, graphic UI and sequencer
This build requires a Teensy 4.1, PCM5102 Audio Board, 320x240 ILI9341 SPI Display with Capacitive Touchscreen and a serial Flash Chip.
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 first generation, MicroDexed-touch offers 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

This is a port of the original Dexed/msfa engine (see https://github.com/asb2m10/dexed and https://github.com/google/music-synthesizer-for-android) to be used on a Teensy-3.6 or Teensy-4.1.

Buttons / Encoders
A quick guide how the push Encoders are working:
Usualy [SHORT PUSH] Encoder Left brings you back to the main menu or closer to the main menu one step.
Usualy [SHORT PUSH] Encoder Right selects or confirms an input/menu item/goes deeper into this item.
In most menu settings of dexed, [SHORT PUSH] Encoder Right, switches between the 2 dexed Instances.
In microsynth, [LONG PUSH] Encoder Right, switches between the 2 microsynth Instances.
in Voice select (dexed) : [SHORT PUSH] Encoder Right switches Instances, [LONG PUSH] Encoder Right switches betweens Banks and Sounds. [LONG PUSH] Encoder Left selects/unselects Sounds to the Favorites list.
In Menus that need 2 Encoders, Encoder Right controls Y movement and Encoder Left controls X movement (for example in Song mode)
