The Voltage Block is an 8 channel 16 step sequencer with a unique user interface. Rather than a slider for each step, there is a slider for each channel and a button for each step. The button may be held with the value input by the channel slider. Additionally, each channel slider can be moved as the sequence is running to input values, functioning more like a knob recorder.
The Voltage Block has built in pitch quantization but is also commonly used for CV modulation of parameters and can work in smooth or stepped modes.
This module is in great shape with just some light rack rash, includes original box.
