"One Bitranger with Synapse matrix keypad, original manual and 12 DuPont pin patch cables

Excellent condition, does not include battery or PSU

The bitRanger is a patchable analog logic computer that sculpts sonic worlds ranging from data noise to melodic arpeggios. While being a handheld standalone synth, it is also right at home in the music studio. Extensive connectivity makes it so flexible that it can connect to almost anything: CV control its unique sound, sync it with drum machines and sequencers or use it as an algorithmic CV / GATE pattern generator.

Go nuts! Bit nuts!

The patchbay of the bitRanger is a place for exploration where you can simply connect outputs to inputs to see what happens. This can be done methodically or with complete experimental abandon. Go nuts! Battery Power and a built-in speaker make the bitRanger totally portable. Tweak it’s 4 knobs, 8 switches, and more than 100 patch points in the woods, on the beach, on a train, and in the studio.

Features

LFO clock oscillator for rhythmical modulation

VCO oscillator is synced to the HFO oscillator

4 modes of operation selectable by 2 switches

built-in speaker with volume control

On /Off switch

expansion connector

package includes 3 photo resistors – make your oscillators respond to light by plugging these into the Bend socket


Patchbay

118 jumper cable patch points

each oscillator has 3 differently slewed CV inputs, sync inputs, rate knob, and bend points

Divider Bits section – use clocks at a different speed to create patterns

Adventure Bits section adds irregular rhythmical elements

MUX 1 and MUX 2 input sections to modulate data loops and waveforms

stereophonic output from MUX 1 and MUX2 sections

BYTE CV section is R2R DAC converter which takes bits and converts them to CV

DATA modulation section witch a switch adds more flavor

Utility Belt section adds advanced features

Left and Right audio override section

External connectivity

3.5mm stereophonic headphone output

Clock Input to sync the LFO oscillator

Clock Output with selectable LFO division (2 or 32)

CV Output from the BYTE DAC section

CV Input for the VCO

CV In and CV Out connectors can be routed to dedicated patch points on the patchbay

Comes with Synapse matrix keyboard

The synapsis is a 4×4 pushbutton matrix that offers performative control of the Bit Ranger.

There are 8 patch points connected to 4 rows (ABCD) and 4 columns (1234) of buttons. Pressing button A1 connects point A to point 1. A2 connects A to 2. B2 connects B to 2 and so on.

Using the Synapsis:

It is best used by dedicating rows to outputs (like divider or mix bits) and columns to inputs (like the byte section or inhibit points). In this configuration every possible combination of buttons will connect outputs to inputs and cause a change in the behaviour of the BitRanger. As always it is best to experiment and try new things."
