The 2655 Geo-Gruvn is a six channel, 16 step Euclidean rhythm / gate sequencer for Eurorack modular synths in only 6 HP.

Geo-Gruvn is inspired by the brilliant efforts of Japanese designer Hagiwo, and produced by SSL with kind permission.  SSL has also significantly enhanced the hardware and software leading to better performance and improved functionality.

Each of the six output channels allow adjustment of:

Hits – The number of outputs generated, with Euclidean spacing.
Offset – Changes the starting point for the Euclidean sequence.
Length – The number of steps for this channel before resetting.
Mute – Turns on/off all outputs of the selected channel.

A single rotary encoder allows uncomplicated selection of channels and functions with simple visual feedback provided by a bright blue OLED display.

In addition to its extensive Clock / Sequencing related duties, Geo-Gruvn can respond to Clock inputs well into the audio range, making it a convenient 6-channel frequency divider.

A Pattern Memory screen allows non-volatile storage for up to 8 pattern sequences.

The Geo-Gruvn features a bright OLED display, clock and reset inputs, 6 gate / trigger outputs, a rotary encoder for selecting functions, and an eight Pattern non-volatile memory.  All inputs and outputs are standard 3.5mm phone jacks with an associated LED panel indicator.

Power is supplied by standard 10 pin Eurorack power header.

Quality, solder masked, fiberglass-epoxy printed circuit boards and meticulous hand-crafted assembly assure years of trouble-free service.
