Two Kicks Eurorack jam - Hexinverter Mutant Bassdrum .v. Dijkstar RiDrum Tk-01 - Acid Techno Jam

Published on Sep 25, 2017 While We Were Sleeping

"A dub Acid techno jam starting my two eurorack kick drums:
* Hexinverter Mutant Bassdrum - A 808 kick with extended range and functionality
* Dijkstar RiDrum Tk-01 - an 808 and 909 highbred kick

!! Warning - This video contains flashing images !!

This is not a comparison or feature review but a fun jam. The Malekko VARIGATE 8+ is used to sequence the two kicks.
* The RiDrum Tk-01 is playing a traditional 1/16 steps (1 bar)
* The Mutant Bassdrum is playing 1/2 steps (8 bars) with random repeats on each step.
The Malekko VARIGATE 8+ is also used to control all the other drums + the 303 bass line and the FM sound.

The complete list of eurorack modules:
Malekko Heavy Industry VARIGATE 8+
Hexinverter Mutant Bassdrum (808 style kick)
Dijkstar RiDrum Tk-01 (808/909 style kick)
Hexinverter Mutant snare (808 style mutant)

Dijkstar RiDrum TK-09 Now on Kickstarter with Random Drawings for Free Units

On kickstarter here.

"You wanna win a RiDrum TK-09?

Then help us to bring the RiDrum THC-01 Handclap kickstarter project to life!

For each 50e backer we gonna choose a random backer who wins a RiDrum TK-09!

You don't need the new THC-01 Handclap but wanna win a TK-09 Kick and know somebody who maybe interested in the THC-01 Handclap?

Tell that person about the THC-01 Handclap and if that person back our project he can put your name on the list so you can also be selected to win a TK-09 Kick.

Thus for the first 50 backers we select a random winner from the backerslist, or a person stated by a backer, but only if there are 50 or more backers, by each next 50 backers we select a second TK-09 winner, so by every 50e backer we give away a TK-09!

At the end off the funding period we randomly select the winner(s) off the RiDrum TK-09 Kick."

"The Handclap proto is finished, and it sounds great, it’s almost identical to the original 808 handclap but with some extra features like tune, claps speed and claps count, the 808 clap is built up with 4 “claps”, in other words there are 4 short noise pulses with a short decay that makes the “crackle” or clap sound and they are all fixed and not adjustable but with this new module you can choose how many claps or noise pulses you want from 1 to 10 and you can adjust the speed of the claps, the speed is also controllable with a CV source.
Also in the original handclap the last clap or pulse has a longer decay time and that’s also adjustable on this new module.

And there is a tune parameter on this handclap, maybe the first analog handclap with tune and this is done with a BPF filter, a handclap is generated with a noise source and noise has normally no pitch, but to generate a handclap with noise, the noise is equalized with a sharp boost in the mid frequencies and vary the boost frequency simulate a nice tune effect, the tune is also controllable with a CV source.

For the ambient noise, or the “reverb or hall noise”, there is a level en release parameter added.

This module will also get a new design compare to the TK-09 Kickdrum, the module will be smaller, 14HP instead of 20HP and the 6.3mm jacks and PSU are being replaced with 3.5mm mini jacks and eurorack PSU socket and to make the modules smaller the internal electronics are built up with modern SMD technology, with normal THD technology it’s not possible to made it fit on one circuit board.

Therefore the TK-09 Kickdrum will also get a redesign to fit with the Handclap, see for more information the Kickdrum page."

"A demonstration of the prototype RiDrum TK-09 Kickdrum based upon the Roland TR909 Kickdrum, for more information check out www.dijkstar.com"  The site lists additional drum modules.

"The RiDrum TK09 is based upon the famous 909, the analog electronic circuit is almost identical and it's extended with a trigger and CV inputs, parameters for the Attack, envelop generator parameters for pitch and a LED to see triggering.

Because the original parts like the transistors and integral circuits (Operational Amplifiers) not being manufactured anymore, they are replaced by standard European components, this had some influence on the overall sound, but with fine-tuning the circuits on the new components it’s almost identical as the real thing, this is the closes you can get compare to the real 909..."
