xr-1 909 groove test


"Testing applying a 909-style groove/swing in varying amounts on the xr-1"

via Reddit 2 days ago:

"Hey all, 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.

Lots more details to come.

I will be demoing this at the Machina Bristronica festival in Bristol next week (flying all the way from the metro Detroit area, first time overseas). If you’re able to make it, come by booth (My business name is Audio Enjoyer) and say hi.

I will launch a signup page later this month and post here again so you can sign up for more info."

Kijimi VCA RC Filter Demo

video upload by Sonic Sand Castles

"This is an A/B test of an RC filter PCB I made to filter out unwanted amp envelope artifact/aliasing noise on the Kijimi voice cards due to low-res DAC amp envelope outputs going into the VCA CV inputs, compared against the default AS3360 DIP ICs.

The PCBs I made just put an RC filter in front of the VCA CV inputs of AS3360D (SMT version) ICs.

The RC filter values are:
- 1k ohm resistor
- 0.47uF capacitor

This was just a quick reversible solution I put together, no direct soldering required on the voice cards or main board.

The first section demonstrates the unwanted aliasing using the default DIP ICs compared to the adapter PCB which filters it out.

The second section demonstrates how the adapter board reduces the strength of the envelope (which is a drawback, but I prefer that over the artifact noise)."

"Ran a MIDI file of 'Everything in Its Right Place' by Radiohead through the Kijimi. Limited the Kijimi to five voices (to better reflect a Prophet 5).
