Turn a handful of open‑source parts into a deep, performance-ready groovebox that feels like a finished instrument instead of a science project. PMicroDexed Touch takes the MicroDexed engine and wraps it in a fast Teensy 4.1 platform with a bright 320×240 TFT touchscreen, giving you a graphic interface where multiple parameters, mixer levels, and sequencer tracks are always just a tap away.
At its core you get four instances of six‑operator FM synthesis plus two virtual‑analog monosynths with oscillator, PWM, multimode filter, and noise, backed by an eight‑voice polyphonic engine inspired by Mutable Instruments Braids for rich digital textures. A chromatic sample player with pitched drum and instrument playback runs from SD card and PSRAM, so your kits and one‑shots stay close at hand even in complex arrangements. The dual sequencer design combines an 8‑track pattern/chain system with a 12‑track Live Sequencer, both fully synced, with chord playback up to seven notes per step, arpeggiator divisions from 1/8 to 1/64 including Euclidean patterns, and a touch mute matrix for fluid live improvisation.
Global plate reverb, two tempo‑syncable delays (extended to long, atmospheric times with an added PSRAM chip), and a four‑band multiband master compressor glue everything together, giving your DIY box a polished, finished sound. USB and TRS MIDI let you drive external gear or control the internal engines from keyboards and controllers, while a web‑based remote UI mirrors the touchscreen for file management, transfers, and hands‑on editing from your computer. Open‑source to the core, PMicroDexed Touch invites you to build, hack, and extend a portable groovebox that’s equally at home as a standalone all‑in‑one rig or the digital brain of a larger hardware setup.
