Dutch Modular Fest

DIY KITS

Timo Rozendal’s passion for technology and sound converge in the realm of electronic music.

Timo’s journey of creating electronic music stated in the late nineties and in 2015 he started designing and building his own eurorack modular synthesizers.

Kit’s timo is taking with him to DMF 2024 for you to solder:

For DMF’24, Timo brings his self-made modules to life, expect a good dose of groove and swing! With three thriftstore cases full of analog and digital modules and a spaghetti of cables, Timo pushes the boundaries of sound and beats. The result is a both nostalgic as well as innovative musical investigation, infused with influences from classic 90s electronic music.

FMP / €100

The module is using the Yamaha YM2413 FM chip controlled by a microcontroller to produce percussion sounds. There are 7 parameters that make up the sound that can be set by turning the knobs. With cv it is possible to interpolate between two sets of 7 parameters. This feature turns it into a very dynamic sound generator. There is a second mode that plays back a mix of the internal drum sounds, in this case you can only set the level/mix and global pitch of the 5 drum sounds. It is possible to save the settings so that it will sound the same on the next startup. The module is by nature lofi and the cv inputs can be noisy, so that means there will often be a variation in sound depending on knob settings.

In Tone mode the module is a 2 operator FM synth voice with a carrier that is modulated by a modulator. This modulator can also modulate itself (feedback). The module can make a wide range of sounds, from clean tones, deep kicks, noisy hats/snares, bell like sounds and even polyphone chords.

3394 VOICE / €100

New analog synth voice based om CEM3394. Compact, beautiful sounding and versatile voice, easy to build.

USBPowerThingy / €25

Simple power supply powered by 5V usb, such as a powerbank or a phone charger. It is fun and useful, especially when travelling, but don’t expect ultraclean power.

DC coupler specs (factory): Maximum input current 1.8A  (and the 5V usage will be added to this)

Maximum output current : +12V is 700mA,-12V is 150mA
(I haven’t tried testing to reach the actual limits, so these numbers are hypothetical, I would recommend to keep the combined -12V  and +12V usage below 400mA)
