USER MANUAL

MSW-820 is a 2 oscillator based analogue monosynth with an advanced 16 mode voltage controlled filter, 2 envelope generators, digital LFO with sync and trigger functions, digital noise source with 8 flavors, MIDI (TRS or USB), all in a compact desktop or euro format.

Specifications:

VCOs

• AS3340 Based, Pulse and Sawtooth Waveforms
• ENV Modulation (OSC1, -5 to 5) and LFO Modulation (OSC2, 0-10)
• Range: 16'/8'/4', 7 Octaves
• Pulse Width Modulation: 50% to Min
• PWM Mode: ENV/Manual/LFO Modulation
• Master and OSC2 (offset) Tune Control
• Pulse/Sawtooth Mixer control per Oscillator
• 2 Hard Sync Modes: O2 Track Pitch or O2 Do not track pitch
• 2 Reset Modes: Reset O1 on gate or Reset O1 and O2 on gate

Sound Mixer 

• External Input (pre filter)OSC 1 Level
• OSC 2 Level 
• Sub Osc Level tracking OSC1 with 1, 2, and 2 PWM Octave Settings
• Noise Level with 8 Noise Models:
  White, Pink, Hex Invert, Crackle, Orgone (pitched), Sonar (pitched)

VCF

• AS3109 Base16 Modes.  Low Pass, High Pass, Band Pass, Allpass (aka Phase)
• Cutoff Frequency: 10Hz to 20kHz
• Resonance: 0- Self Oscillation
• CV Follow: 0-100%
• "This" knob (Audio rate filter modulation from OSC1's triangle output)
• Envelope Modulation via Attenuverter (-5 to 5)
• LFO Modulation via Attenuverter (-5 to 5)
• Pitch Modulation via Attenuverter (-5 to 5)
• External CV Modulation via Attenuverter (-5 to 5)

LFO

• Rate: 0.1 Hz to 22 Hz. 8 Shapes with crossfade between shapes:
  Sine, Square, Ramp, Tri, Saw, Expo Decay, Random, Smoothed Random
• 2 Reset Modes.  Reset on Gate and Reset on Gate with Phase Control (via Fade knob)
• Fade Control: LFO Delay (Reset off, Reset Mode II) or LFO Phase (Reset Mode II)
• Bipolar Rate indicator 

Envelopes 

• Attack time: 1.5 ms to 2 s
• Decay time: 2 ms to 10 s
• Sustain Level: 0-100%
• Release Time: 2 ms to 10 s
• Modulation Envelope is hardwired to Modulation bus
• VCA Envelope is hardwired to VCA

Portamento

• Main Pitch (Master Tune) slide

Accent

• Two Modes: Accent on VCF, Accent on VCF and VCA
• Accent level controlled via EXT mod slider

VCA/Output Mixer/VCA 2 

• Synth VCA Control
• External Input (Thru, VCA2 via MOD Env, VCA 2 via EXT CV)

Inputs/Outputs 

• MIDI IN. TRS 3.5mm PSIMIDI (either A or B)
• Clock IN to Control LFO Rate**
• Gate IN. 5-10V*
• V/Oct IN*
