PWM Audio Out (Unipolar, Line Level) L/Mono: Pin D5 (or D6), R: Pin D11.Even using only the power supply adapter significantly reduces USB noise.To use MIDI Shield (or MIDI Breakout), take #define SERIAL_SPEED (31250) (31.25 kbps) in "DigitalSynthVRA8Q.ino".NOTE: A combination of a MIDI Shield (or MIDI Breakout) and a power supply adapter is better to avoiding USB noise.We recommend Hairless MIDISerial Bridge to connect PC.v1.0.3: Fix the problems with bass or treble note on.v1.1.0: Change the behavior of the oscillators.v2.0.0: Add Mono and Stereo 2-phase Chorus modes Improve the pitch Introduce No Decay (DECAY = 127) Improve the recommended circuit Other changes.v2.1.0: Improve sound quality Change PRESET Other changes.v3.0.0: Improve sound quality Fix Oscillator pitch Increase the CUTOFF frequency slightly (min: 880 Hz, max: 14.08 kHz) Change the Q range of RESONANCE (min: 0.7, max: 8.0) Increasing RESONANCE decreases the filter gain Support Velocity > CUTOFF (OFF/ON) Reduce pop noise when turning notes ON and OFF Enable Short Delay FX Change PRESET programs Support All Sound OFF and Reset All Controllers Other changes.v3.1.0: Fix the problem pitch bend is minimized by Reset All Controllers Add VOICE Mode (PARA/MONO) Expand the range of CUTOFF frequency (min: 440 Hz, max: 14.08 kHz) Improve VELOCITY > CUTOFF Fix the instability of the pitch when a note (Gate) is turned on Change PRESET Other changes.v3.2.0: Add Pseudo-Stereo Chorus Mode Assign free voices in Oscillator index order Change CPU Busy LED lighting condition Other changes.v4.0.0: Add PORTAMENTO Time Remove AC coupling capacitors from the recommended circuit.

v5.0.0: Fix wave tables (Reduce noise) Change the range of CUTOFF frequency (min: 452.9 Hz, max: 14.5 kHz) Improve LFO RATE (min: 0.2 Hz, max: 20 Hz) Add EG > PITCH, LFO WAVE, LFO FADE TIME, MONO OSC2 MIX, and MONO OSC2 DETUNE Add Legato Mode (Monophonic, Single Trigger, Auto Portamento) Change the recommended circuits Rename PRESET #7 NEUTRAL to INITIAL Other changes.
