Programming the bass sound of West End Girls on a Frap setup was a tough challenge (but we did it)

video upload by Frap Tools

"So we were asked to remake the bass sound of West End Girls by @officialpetshopboys with only Frap modules, and here's how we did it! It's not completely there but still seems like a fair approximation. Got other ideas? Let us know in the comments!

A patch inspired by sympathetic strings with FUMANA

video upload by Frap Tools

"This FUMANA patch draws inspiration straight from sympathetic strings, a device that can be found on many instruments like the European nyckelharpa or the Indian sitar.

The legend of BRENSO’s pulse-width modulation

video upload by Frap Tools

"PWM is a huge part of everyday electronics, but it is also a classic synth sound, to the point it reached a cult (if not meme) status.

A Eurorack oscillator like BRENSO wouldn't have been completed without a PWM section, and today we're exploring it in detail. It might not be the most obvious feature, since it is nestled into the timbre modulation section, but it is capable of wild timbers.

"A recent article on @PerfectCircuit’s blog inspired this exploration beyond the label of "West Coast" synthesis. We thus focused on two techniques for the BRENSO oscillator that go beyond the classic complex oscillator's palette: PWM and sync."

"We started from the overtone series and we arrived at Western tonal harmony. However, we left something behind: the modes. In today's video, we'll see what they are, and why they seem such a vague concept."

Frap Tools: We used our CUNSA quad multimode filter as a phaser.

video upload by Frap Tools

"Is it a phaser? No! Will this stop us from using it as a phaser? Also no!


Today we take advantage of the phase rotations introduced by four 12-dB/oct filters to create a fake analog phaser with surprising effects."

How to shift gates to spice up a boring sequence on the USTA | Frap Ideas

video upload by Frap Tools

"This patch came up during a past live workshop on the USTA sequencer. It was an advanced session and one of the main questions was: 'how can I get enough variation on a repetitive loop?'

While talking with the attendees, especially Cameron and Rayhan, we found that the gate shift function combined with a mild cross-patching could have been an excellent starting point, and so here it is for all of you to check out.


00:00 Introduction and patch overview
01:50 Using the gate shift function to add groove
04:33 Using a second pattern to shift the gate length
06:16 Ratcheting shift
