MidiVolts Desktop | Moog Mavis
video upload by Space Brain Circuits
"A little demo on using the Moog Mavis with the MidiVolts Desktop. The LFO rate CV response is good for only a couple octaves. Nonetheless, you can still get some cool results. Thanks for watching!

Poly Sequencer V3 | Getting Started
video upload by Space Brain Circuits
"The POLY SEQUENCER is a MIDI based polyphonic step sequencer that records up to 128 steps. The Poly Sequencer works by recording a sequence by a MIDI controller, and outputting the recorded sequence via an external MIDI enabled device. The Poly Sequencer’s tempo is controlled by the Internal Clock by use of the Tempo Knob or Tap Tempo. However, the Poly Sequencer may also be synced to external gear by use of the Gate In, or receiving MIDI Clock messages. The rate at which the steps are sequenced is controlled by the Division section, representing the number of steps played per clock. By Default, the Poly Sequencer can store up to 5 notes per step with 1 Velocity and 1 CC reading, however the user may choose to change the Sequence Type which varies the stored data depending on the mode selected. Additional functionality includes saving, auto generating blank sequences, as well as step override/ interrupt/ transpose during playback. Firmware versions may also be upgraded by USB connection.

Sequence Types:
The Poly Sequencer’s operation may be adjusted depending on the Sequence Type selected. The Sequence Type defines what type of data is stored for each step. For Example, Mode 0 stores up to 5 notes, with 1 Velocity and 1 CC reading per step.
Mode 0 (Default): 5 Notes, 1 Velocity, 1 CC
Mode 1: 4 Notes, 2 CC
Mode 2: 4 Notes, 4 Velocity
Mode 3: 1 Note, 1 Velocity, 3 CC
Mode 4: 0 Notes, 3 CC
Mode 5: 8 Notes
9V center positive DC adapter not included."

Space Brain Circuits DarkSky-4 | Stereophonic Analog Polysynth
video upload by Space Brain Circuits
"All sounds are directly from DarkSky-4 without any external effects or plugins.
User manual: https://github.com/SpaceBrainCircuits..."
New synth priced at $699.00, from the maker of MidiVolts.

"DarkSky-4 is a 4 voice stereophonic analog synthesizer.The synthesizer consists of 4 independent oscillators that can be played monophonically, paraphonically or polyphonically. Each oscillator is equipped with a dedicated VCA and Envelope, which allows for better musicality and the ability to sound each note as it is pressed. Each oscillator contains a sawtooth and square wave, which can be mixed to generate various timbres and sounds. The square waveform can be gradually adjusted from a square waveform to a narrow pulse width waveform to further expand the sonic characteristics of the oscillators. The synthesizer also features two 24dB low pass filters with dedicated controls for cutoff frequency and resonance peak. DarkSky-4 provides several ways to add modulation to the audio signal, including frequency modulation, pulse width modulation, and filter modulation. The unit was designed to create a more expansive soundscape for studio and performance settings. The filter adjustments, along with filter modulation, provide a wide range of stereo effects when in stereo mode. Additionally, the semi-modular patch bay can be used to further modulate multiple sources of controls."

"The MidiVolts Desktop is a MIDI based 5 octave CV controller. The device contains 4 separate CV outputs with an associated Gate output. These CV outputs are called voices, and are named V0, V1, V2, V3. Each voice operates on the 1 volt per octave standard for eurorack and most hardware synthesizers. The device uses 6 different modes (MONO, DUO, UNISON, POLY3, POLY4, CC) to control each voice in different ways. See below for descriptions of each Mode. The device also contains a Midi to Clock output conversion and further customizations with SysEx midi messaging.
