another drum machine

video by wildchurch

"Quick overview of another drum machine: lo-fi 8 bit samples with pitch control, panning and FX insert options

Built around the following:
- LMNC's Big Button sequencer: https://www.lookmumnocomputer.com/pro...​
- Drum samples on six ATtiny85 chips - using Jan Ostman's Drum Creator tool: http://synthworks.eu/attiny85-drum-cr...
- MFOS Ultra-simple Mono-in Panning Mixer: http://musicfromouterspace.com/analog...

I've added inserts to the first 3 channels of the mixer to allow FX send and return

I also wired up the big button for afterlife's MIDI upgrade: [video here] ..but it doesn't seem to behave well with this build so currently I've got the original code installed on the arduino until I resolve the issue

Cheers"

minipops 2O2 ~ breakbeats 'n' stuff

"a build of jan ostman's O2 minipops arduino drum machine with different samples and patterns

first a quick run through of the patterns/samples:
~ there are 12 patterns selected by push buttons
~ i've added kick, snare, tom, hi-hat and cymbal derived from 808 and casiotone! samples while retaining the original cowbell, clave and maracas

second part shows some MIDI clock sync'ing along with triggered filters via the analog reset out
~ an arduino MIDI sequencer/arpeggiator: http://brendanclarke.com/2014/04/23/a... drives a Yamaha WT11 with patches
~ the WT11 stereo out runs through separate filters for left and right
~ the minipops reset out tiggers an ADSR (via clock divider and trigger to gate conversion)
~ ADSR output goes to buffered multiples to produce two signals - one to each filter's cv input"

The Arduino-Solina V2.0

Andreas Remshagen

"I experimented with Arduino-Synthmaking and found an Arduino-Solina String-Synth Device running with Midi made by Morocco Dave and Jan Ostman. I made a modification by adding a second Arduino for building a Stereo-Device for a lusher String-Sound.

Yah, i know its not a real solina or a strings synth but i never had build such a Device easier and cheaper.Its a nice Solution for using strings-effects. I only use the clean sound in this video-if you take effects as reverb, delay, phaser and a filter you will get a very nice sound

Here you can download Morocco Daves modified circuit:

Thanks to Jan Ostman and Morocco Dave for sharing their ideas"

Overview: SOLINA String Synth for AE Modular #TTNM

Published on Feb 25, 2020 THE TUESDAY NIGHT MACHINES

"If you're like me and miss lush pad sounds in your modular synthesizer, then this module might be right up your alley! MORE INFO BELOW :-)

♥ SUPPORT: http://bit.ly/ttnm-support ♥

The SOLINA String Machine module is based on Jan Ostman's DSP code and adapted for the AE Modular synthesizer format. Create a variety of chords easily, sequence them and then shape the string sound to you liking with oscillator spread, a filter, vibrato and a phaser. The module also plays incredibly well with other effects from the AE Modular synth module lineup."

The Breadboard-TS Development Synth

Published on Oct 7, 2017 Jan Ostman

"This is the Breadboard-TS Development Synth.

The Audio is from the internal test square oscillator played both with the touch keyboard and a MIDI-keyboard.

The scope shows the signal in realtime.

Any chips from http://www.dspsynth.eu can be inserted into the breadboard and played with the built-in MIDI2CV interface.

The Cheapest Drum Module

Published on Oct 7, 2017 Izhar Ashdot

"This is probably the cheapest drum module available.
It's based on an ATtiny85 chip, the code was written by Jan Ostman [of DSP Synthesizers] and it's open source.
All you have to do is build it!"

Infinity37 First DCO test

Published on May 14, 2017 Jan Ostman

"The Infinity37 is a fully polyphonic analog hybrid synthesizer using the Polytron37 chip.

This is the first test and it is just the square wave output of the chip with no filter.

DSP Synthesizers Micro-TS - Keyfob Touch Synthesizer - The Tiny-TS Goes Micro

Published on Feb 28, 2017 Jan Ostman

via DSP Synthesizers

"Being only keyfob size, 61x41mm, the Micro-TS IS the smallest playable analog synthesizer in the world.

The Micro-TS – Keyfob Touch Synthesizer

If you think the Tiny-TS is small then think again.

The Micro-TS is keyfob sized, 61x41mm but still features the same specs as the Tiny-TS.

It runs on 3V so a CR2016 button cell works just fine.

The analog knobs have a trim potentiometer footprint.

Output is a 3.5mm stereo headphone jack.

It still has CV/Gate outputs but they are just pads on the PCB edge.

Available from 1st of March.

Only 50 available in the first batch."

DSP Synthesizers JVS-01 Semi Analog Synth Voice

Published on Feb 24, 2017 Jan Ostman

"The chip has a Saw DCO, 24dB lowpass DCF with resonance, DCA amplitude and a 512-stage DDL Chorus.

All parameters are CV controlled."

via DSP Synthesizers

"New chip for 2017!

The JVS-01 is a semi-analog synthesizer voice in a 8-pin DIP.

The chip implements a Juno-style synthesizer voice with a saw integrator DCO, 24dB lowpass biquad filter with resonance, DCA with 1024 level amplitude control and a 512 stage DDL Chorus.

The chorus can be turned on or off.

The signal chain is 96dB 16-bit DSP and the DAC runs a 1MHz PDM signal.

Internal processing is done at a 66KHz sample rate.

The chip can be used as a voice chip for an analog voltage controlled synthesizer.

All CV inputs handle positive 0-5 volt input and the DCO pitch conforms to a 1v/Oct frequency response, 5 octaves, 61Hz – 2KHz range."

Tiny-TS Sequencer Demo w/ New v1.1 Firmware

Published on Dec 26, 2016 Jan Ostman

via DSP Synthesizers

"The Tiny-TS is only monophonic and doesn’t have an arpeggiator.

But with the v1.1 firmware it now also handles CV and Gate input from a sequencer to make it play arpeggios.

On startup it checks if the Gate output is grounded.
If it is it reverses the CV/Gate ports to inputs.

The Gate now triggers the envelope and the CV input shifts an octave up on the keyboard.

Voila!
You can now play arpeggios."

DSP Synthesizers Tiny-TS Now Also Available at Hackster.io
