Moog Matriach

semi modular Synthesizer (2019)


Overview and oscillator

Overview 49 Full-Size Keys (FATAR Velocity-sensing with Aftertouch ) is a patchable 4-note paraphonic analog synthesizer with a built-in Sequencer, Arpeggiator, stereo Ladder Filters, and stereo Analog Delay. Considered like a semi modular with 90 patch points. On the left size a modulation and pitch wheel with glide amount and 3 performance keys (transport)

OSCILLATOR 4 analog VCOs ( Triangle, Sawtooth, Square, Pulse) can be split into 4 notes of paraphony that can be sequenced, shifted, and stored with a 256 step sequencer, or stacked in unison mode in 1/2/4 voices, speclaHard Sync and FM capabilities


Filter, EG and LFO

FILTER 2xanalog resonant  filters with parallel  multimode HP/LP , stereo LP/LP and series HP/LP.
External sources can be filtered with line input.

ENVELOPE 2 EG with ATTACK DECAY SUSTAIN RELEASE ADSR can be managed also by patchpoint and of course retriggered.

LFO features six shapes Sine, Sawtooth, Ramp, Square, Staircase, and Smooth Random.


Arpeggiator,  sequencer and memory

ARPEGGIATOR-SEQUENCER 256 Steps with up to 4 notes per step; 12 Sequence locations. They can be synched to masterclock.

MEMORY 128 rom sounds + 128 USER FREE with 11 family instruments for quick retrival. a free utility called  MIDI Control Center  can be downloaded for free from arturia website. 

EFFECTS analog stereo delay based on BBD chips with up to 780 millisecond, can be synched
