The board is made for Thonkiconn jacks and a 6HP panel.

If you dont want to use the board for a euromodule it can be sawed off at the D1-D4 diodes and used for non euro projects.

You can order it for  $45 including international shipping.
Please add a note for what sound you want programmed into the board, DR-55, CR-4 or RW.

December 7, 2015

DR55

Might just be one of the smallest drum machines on the planet! Continuing along in our early drum machines theme is the Dr.Rhythm DR-55.

DR551

This is based on the dsp-D4 chip drumchip.

If you are a eurorack modular enthusiast and have run out of 3U room, this tile makes it easier than ever to add some old school percussion to your rack.

These will be available through our indiegogo campaign.  Please help support us here:  https://www.indiegogo.com/projects/sp-12-drumulator-euromodule

 

dsp-D8/L8 drumchips

dsp-D8

dsp-L8

The dsp-D8 and dsp-L8 drum synthesizer are chips that contains a PCM drumkit in a 28-pin DIP
package.

The D8 have standard drum sounds and the L8 are Latin Percussions.

The chips can be used as voice chips for a drummachine or a drummodule.

They are 8-voice fully polyphonic with 8 separate trig/gate inputs for each voice.
6 of the drums can be separately tuned or modulated by an analog control voltage.
There is an Accent input that boosts all drumsounds by +6dB.

The output is 40KHz 10-bit Sigma-Delta PDM and the chip runs standalone from a
2.7-5 volt power source.

Application manuals can be found at http://www.dspsynth.eu

Order the dsp-D8 for $30 incl international shipping

Order the dsp-L8 for $30 incl international shipping

This is what the dsp-D8/L8 drum chips sounds like out of the box:

These are the chips used in the SP-12 drumulator and Rhythm T727 Euromodules found at http://igg.me/at/drumulator
