Here’s a sneak preview of the new Audio Enjoyer XR-1 groovebox, which will debut at Machina Bristronica, a ‘festival of knobs’, scheduled for Sept 30th, 2023 in Bristol.

Here’s what the developer has to say about it:

“This is a prototype of the xr-1, a digital drum machine, sampler, and synthesizer. It’s powered by the Teensy 4.1 microcontroller.

It’s a 909 style sequencer (a step can be off, on, or accented), with 16 banks, 16 patterns per bank, 16 tracks per pattern, and a max of 64 steps per track.

There are 4 performance modes (tap, mute, solo, ratchet) and a song arrangement mode.

It has stereo in/out (usb audio in the future). It has 5-pin DIN MIDI I/O, 4 pairs of CV/gate outputs (really 8x CV outs with 0V to +10V range).

A micro SD card is used to store/recall audio samples and project data. Samples can be mono RAW or stereo WAV files. Mono samples can be looped.

There are 16 sample voices available, and 4 voices which can be used as synthesizer voices.

I currently only have a simple 2-oscillator subtractive synthesizer right now. More will be added later.

It has a capacitive touch keyboard which is useful for assigning notes to steps, playing while jamming, performing with ratchets at various beat divisions.

Details are still to be announced.
