A quick demo of the Analogue Systems RS-240 Frequency Shifter I bought a month ago and just managed to connect in my eurorack modular. Every sound in the video, apart from the delay, is made with Analogue Systems modules -- still hoping for that sponsoring contract ....
The demo starts with a basic patch of 2 RS-95 oscillators (pitch controlled by the AS Sorceror keyboard), through an RS-165 signal mixer in the RS-110 multimode filter. The lowpass output of the filter then goes in the RS-180 VCA. The VCA and the filter cut-off are both controlled by an RS-60 envelope generator, which is triggered by the clock output of the RS-200 sequential controller. In addition to the envelope output, the filter cutoff is also controlled by the triangle output of an RS-80 VC-LFO. For this the envelope and LFO output are combined in a RS-160 control mixer. The first minute of the video give this untreated sequence. I try pointing out the patch cords and signal path.
After this I plug the output from the VCA in the RS-240 Frequency Shifter. The A (downward shifted signal) and B (upward shifted signal) outputs are send to two channels of my mixer panned hard left and right. The frequency shift is modulated by the output from the RS-200 sequential controller -- so giving a different shift for each step -- and the triangle output from a second RS-80 VC-LFO.
I show the different sounds resulting from varying:
(a) the scale of the RS-240, this switch controls the amount of maximally possible shift from 0 to 5000Hz;
(b) the amount of sweep from the LFO (by varying the output level of the LFO);
(c) the amount of variation from the sequencer (by varying the range of the output of channel A of the sequencer).
After a few minutes I add some delay (courtesy of an Ibanez DM1000 early 80s digital delay) of the mixed output of the RS-240 to give further variation.
This is my first patch with the RS-240 (Bode) Frequency Shifter, but I like the sounds coming from this and there are few demos of this module on the internet so I hope you will enjoy it too.
