"The Atomosynth Mochika 2 custom synth and step sequencer made in Peru.
They are incredibly rare and a very versatile. Can be used with the internal synth sounds and sequencer,
or as an external sequencer with CV and Gate to control other synths.
It can be Midi Synced as well.
Controls and ParametersMain
On/Off switch: It is located in the rear panel, it turns on and off the unit.
Volume: It sets the main volume level.
Noise
Noise On/Off switch: It adds a white noise
Noise Depth: It sets the amount of white noise applied to the VCO (Voltage Controlled Oscillator).
Low frequency oscillator
LFO Wave: It sets the waveform of the LFO (Low Frequency Oscillator) to square wave (up), off (centre) and triangle wave (down).
LFO Depth: Is Sets the amount of modulation applied to the VCO.
LFO Rate: It sets the frequency (velocity) of the LFO; a led will indicate the actual frequency of the LFO.
MOD switcher: in the VCO position it sends the LFO signal to the VCO to modulate it. In the VCF position it sends the signal to the filter and affects the Cutoff parameter
VCO
VCO Wave: It sets the waveform of the VCO (Voltage Controlled Oscillator) to square wave (up) and ramp wave (down).
VCO Depth: It sets the depth of the VCO.
Tune: It set the pitch range of the VCO, it has a huge range, from subsonic (were only the spikes on the wave are heard) to ultrasonic. You can use it to change in real time the tone of all the "Step pitch knobs" at once.
Filter
Cut Off: Set the cut off frequency.
Resonance: add a big resonance feedback.
Sequencer
Seq : It sets the mode of the sequencer: starts and stops the internal clock, or set it to midi synchronization
Tempo: It sets the Tempo (velocity) of the internal clock
Step switchers: These turn on and off each individual step.
Step Pitch knobs: These set the pitch of each individual step.
Inputs and Outputs
Audio Out: Audio output used to connect the Mochika2 with an amplifier or mixer. Use unbalanced ¼" connector (mono plug)
CV Out: Control Voltage Output, used to control other analog synth by the Mochika2's internal sequencer and the step switchers and step pitch knobs. The CV out is controlled by the step pitch knobs, so each step knob can set the CV Out from 0V to +4V. Use unbalanced ¼" connector (mono plug).
Gate Out: sends a +5Volt gate signal .
Midi in: Midi sync input, used to sync the Mochika2.1 with other midi devise. Use standard midi cable.
Synchronization
The Mochika2 can be synchronized with other Midi devices via messages such as Timing clock, start, and stop. (Mochika2 as slave)"
