"Original 1980s unmodified classic,
"Four voltage-controlled oscillators (VCOs) and a noise source are routed through a voltage-controlled filter (VCF) and voltage-controlled amplifier (VCA). It can be used as 1) a four-oscillator mono synth; 2) a four-voice paraphonic synth, with voices cycling through oscillators but sharing a VCF and VCA; 3) a shared mode using mono mode for single notes, dual oscillators per note for double notes, otherwise paraphonic mode; 4) a chord memory which results in a mono synth albeit with four oscillators playing notes of up to a four-note chord.
The four VCOs have controls for independent tuning, footage (16, 8, 4, 2), waveshape (triangle, saw, pulse-width, and pulse-width modulated), and amplitude. These are implemented with SSM2033 chips. Portamento may be used for VCO frequency. The noise source has a level control. [1]
The single VCF is a 24/dB octave low-pass filter, with controls for cutoff, resonance, scaling, and invertible envelope control. It can self-oscillate, and be scaled 1:1 with frequency, and thus used as a fifth oscillator. It is implemented with the SSM2044 chip.
There are two envelopes. One is dedicated solely to the VCA. The second in nominally the "VCF envelope" but can additionally control VCO pulse-width, all VCO's pitch, pitch only of VCO's 2 and 4, and frequency modulation amount. The envelopes share controls for single or multiple trigger, and damping.
There are two low-frequency oscillators (LFOs), called "Modulation Generators" (MGs) by Korg. The first has control over waveform and speed, and can be routed to VCO pitch or pulse-width, VCF cutoff, and frequency modulation amount. When controlling VCO pitch, it can control all VCOs; VCO 1; VCO 2, 3, and 4; or VCO 2 and 4. The second only has a control for speed, and can control the arpeggiator or VCO pulse-width.
There is an arpeggiator with on/off/latch control, up/down/up-down pitch control, and 1/2/full keyboard control.
The Mono/Poly includes extensive and significant modulation capabilities between the oscillators, grouped in a section captioned "Effects." These include the abilities to: 1) sync VCO's 2, 3, and 4 to VCO 1; 2) sync VCO 2 to 1, and 4 to 3; 3) to frequency-modulate VCOs 2, 3, and 4 with VCO 1; 4) frequency-modulate VCO 2 with 1 and 4 with 3. Oscillator sync and frequency modulation can be used together. This ability to have 1 master with 3 slave oscillators, or 2 each, is leveraged by the bewildering variety of oscillator subsets that can be controlled with modulation sources and wheel controls.
External inputs and outputs are provided for CV/Trigger, VCF and VCO mod inputs, arpeggiator, and portamento. The pitch bend and mod wheel can be assigned to control pitch of all VCOs; VCO 1 only; VCO 2, 3, and 4; or VCO 2 and 4. The pitch bend range extends to 2.5 octaves for VCO pitch, and the audio range for VCF cutoff."

"Works good. Some damage to bottom edges. Joystick is bent. Number 1 button sometimes re-triggers. See pictures.
This was Korg's answer to the Roland Juno-60 and it looks like a Juno-106 but the Poly-61 is more interesting in many ways.
Features:
- Six-voice polyphonic analog synth with digital controls
- Two digitally-controlled oscillators using square/pulse or saw waveforms
- Arpeggiator with latch, one-, two- or full octave range and up, up/down or down modes
- Polyphonic and Chord Memory/mono (unison) modes
- Hold button (any key pressed stays on until polyphony reached or turned off)
- Pitch bend joystick with DCO (pitch) modulation (up) or VCF (filter) modulation (down)"

Introducing Tyso Daiko - Dual Wavetable Drum Voice - ALM031
video upload by ALM TV
"Introducing the TYSO DAIKO, the successor to the recently retired Dinky. The ‘Tyso Daiko’ updates our unique 12 bit drum module with another voice, new features, capabilities and improved control.
The Twin voices are independently triggered and output, but share pitch, envelope and other parameters of a swept wavetable oscillator (with updated waves). A ‘surface’ control to adds optional additional ‘punch’ or attack to output.
One voice is output through a voltage controlled analog tilt EQ emphasising upper or lower frequencies. The other voice is output through a digital wavefolder which adds increasing timbre complexity reaching noise. Voices also feature accent and choke control (voice 1!).
Full voltage control including a V/Oct pitch input makes the Daiko a fun, expressive and wide ranging drum module with extremely wide pallet of sounds with lots of modulation possibilities.
In this video we take a look at all the features and build some patches with the Daiko as the centrepiece.

Prophet Rev2 Stretchweaver music-box mechanism Gecho Loopsynth | minimal ambient melodic experiment
video upload by Nate Connelly
"Music Box, Gechological Gecho Loopsynth v2, Sequentail Prophet 8 Rev2, Drolofx Stretchweaver. Ambient melodic electronic musical looping & sequencing experiments.
The gecho / music box loops are going into channel 1 of the drolofx stretch-weaver - the prophet Rev2 into channel 2 of the stretch-weaver. The Rev-2 is playing a programmed chord sequence in the same key as the melody on the music box. Stretchweaver is on the gate setting. The Gecho music box loops are opening the gate for the Rev2. You can hear how I am adjusting the amount of the Rev2 the music box loops are allowing through. Everything is going through the strymon big-sky, because life is nothing without reverb.
