Michigan Synth Works Threshold - Edges clone with midi expander 2019 Natural Aluminum

Please direct any and all support questions to Mi Synth Works, NOT MUTABLE INSTRUMENTS. This is NOT an Mutable Product and under no circumstance do you need to bother them with anything related to it.

Threshold is a quad chiptune generator based on open source Edges. This device features PSImidi which allows ANY type of TRS midi cable to be used on the input. Type A or B, male or female, all will work. (not included)

10HP
3 Square/pulse generators

• Aliasing-free digital synthesis, based on a 4 MHz digital timer.
• 5 preset duty cycles settings, from 50% to 95%, or CV-controlled PWM.

1 Noise and triangle generator

• 48kHz, 12-bit DAC without reconstruction filter for a raw sound.
• Triangle, bitcrushed sine, steppy NES triangle or various flavours of LSFR noise.

Advanced features

• Optional semitone quantizer on the pitch CV input.
• Per-channel mini step sequencer (8 steps) – perfect for creating rapid fire arpeggios. When the sequencer is active, the GATE input works instead as a CLOCK input.

MIDI Functionality

MIDI Learn: Press this button and send a midi note. The device will use that channel as the base channel

MIDI Mode: This button cycles between two operational modes.
1. 4 single voices trigger on 4 midi channels starting on the base MIDI channel (i.e. base channel is channel 2 so the voices are mapped over channels 2, 3, 4, 5)
2. Simple Poly mode where each voice plays on a different note on the same midi channel

Note about MIDI and Gating: The gate is normalled OPEN by the Gate 1 input. This is by design but will also force the gate open when the device is triggered by midi. Placing a dummy jack will break the open normal the gate will trigger via MIDI normally
