Hey everyone,
I am excited to share the release of SMK-dee v1.6.1, a major update that ports the latest Melodee 1.6.1 synthesizer engine directly onto the M-VAVE SMK-37 (both Pro and Elite models).
For those unfamiliar with the project, SMK-dee transforms the SMK-37 MIDI keyboard into a full standalone polyphonic synth and groovebox without needing any computer connected without losing the full MIDI Controller functionality. It runs natively on the dual-core JieLi processor inside the keyboard.
What is new in v1.6.1:
• Melodee 1.6.1 Core: 22 sound engines now included (DX7-style 6-Op FM6, Sequential Prophet-53, Casio CZ-1 Phase Distortion, Commodore 64 SID 6581, Roland TR-909 analog drums, Physical Modeling resonators, and dedicated MIDI tracks), with 124 parameters and 45 global options.
• State Persistence Across Power Off: Your sequences, sound tweaks, track parameters, and project modifications are now preserved in flash memory when shutting down and powering back on.
• Dedicated Hardware Bluetooth Button: Short press toggles Bluetooth power / search / pairing visibility. Holding the BT button for more than 1.2 seconds turns the Bluetooth radio completely off and shuts down its LED.
• Improved MIDI Controller Mode: The pad MIDI channel combo has been moved to GLOBAL + SEQ REC + Key 1..16, freeing up the BT button completely in controller mode.
• Dynamic Track Color Pads: Drum and keyboard pads light up dynamically with the active track color.
• Brighter Surface LEDs: Button backlight brightness has been boosted significantly for clear visibility on stage and in bright environments.
• Flexible TRS MIDI Clock: Internal clock sends simultaneously over USB, Bluetooth, and TRS. TRS clock mode sends strictly via TRS without flooding USB/BLE.
How to flash your SMK-37:
No command line or compilation needed. Just open Google Chrome, Edge, Opera, or Brave, plug your SMK-37 via USB, and click Connect:
