Hello everyone. I hope we’re all doing ok during these strange times! To give something back to this great community and hopefully something to use in your creations during social isolation, I’ve decided to release my FM drum machine I’ve been working on for quite some time and have been using in my live sets/recordings.
If you find this useful and enjoy what I’ve created and you haven’t been financially hit during these times, please feel free to donate any amount you are comfortable with via Paypal (family/friends payment) to
The synth gods will forever shower you with the purest of sine tones.
This is a 3 voice FM based drum machine using only the aforementioned holy sine tone. (and one slither of noise). The voices are kick, snare and hihats and each voice can increase in sustain whilst varying it’s tonal quality. There’s so many sweet spots on the hihats! I kept the timbre of the kick somewhat more focused than the other two.
The rFM Machine is expecting triggers via A1, B1 and C1 for Kick, Snare and Hihat and the top level controls to the unit are as follows.
Kick - From super tight to huge punches to long pitched shifting kicks.
Snr - From super tight to long sustained FM snare tone. The longer the sustain the higher the pitch so pseudo melodies are possible.
Hats - So many tonal variations from tight pops, clicks, pings, dings all the way up to crazy FM noise drone.
Kvol, Svol, Hvol are the separate volumes for the Kick, Snare and Hats. 1 is default, 0 is silence and 2 starts to overdrive the signal.
KMute, SMute, HMute are the separate mute switches for the Kick, Snare and Hats.
LPF - A master low pass filter to tame the top end if you desire or to create sub rhythms.
All of this takes up approx 30% CPU at 48kHz. This unit has been tested on Version 0.4.27.
Here’s few examples of it in action.
Nothing but the rFM Machine with the 16n Faderbank controlling the unit.
Stripped back rFM Machine tone within a patch.
With some extra massaging from other modules.
Feel free to leave some feedback if you try it out. I’d love to hear what you think of it or to hear it being used it your own creations. The download link is below and if you feel like buying me some beers/coffees/lambos, feel free to paypal me some at firstname.lastname@example.org (family/friends payment). Much love!
You’re more than welcome to have it for free too if you’ve been affected financially by this pandemic or if you just promise to be a nice person and give me a follow on Instagram.
I’m hoping to create an accompanying melodic unit based off of some of synthesis used here if there’s enough interest in the rFM Machine. For those of you have been waiting patiently for me to release this, here you go! And for everyone, I hope you enjoy it and find some use for it.
