RS240 Frequency Shifter
Reaktor realization of Bode Frequency Shifter
This is a reworking of Sean Costello's excellent Bode Frequency Shifter. The actual frequency shifting engine is completely Sean's work, I have added some other features that I wanted and some new skin borrowed from some Analog Systems manuals. The interface is still very rough, but I have moved on to other experiments, so this is as far as I am taking it.
Much like my Roland Space Echo experiment I feel like this is an effect that should be played like an instrument rather than to be left at a certain setting. I have mapped the mod wheel to the big dial because I think it should be in constant motion!
This thing sounds great to me on guitars and vocals. I have bundled it here with Martin Brinkman's excellent BassLine 303 style synth, but I intended it to be used as an insert effect. Bassline is only included here as an example.
Thanks to Jonathan Style for the 3D vintage knobs!
Don't ask me to explain exactly what this device does. It sounds really cool to me. It is related to a ring modulator but is really it's own thing.
The A view is just the big dial module, the B view includes the other modules.
The big dial controls the frequency shift effect.
The scale knob selects the range of the big dial. The zero setting is bypass, the EXP setting is some math operation , then +/- 5 hertz, +/- 50 hertz, +/- 500 hertz and lastly is +/- 5000 hertz.
Zero Adjust is a fine tune knob that has a range of 10% of the big knob.
Mixture controls the crossfade between the two outputs of the frequency shifter engine.
Squelch is the threshold for the input gate. This is here to filter out background noise so the mix doesn't get too nasty. (the controls for the gate attack and release are on the mixer panel)
In the mixer-utility panel we have a dry and wet balance. The input level is a gain stage for whatever is coming in. Saturation is the amount of the saturation effect mixed into the proceedings. Output is the overall output level.
I have patched two LFOs to the main frequency dial. LFO1 is Faster Speed and LFO2 is slower speed. The two position switches in each LFO area control the range of the Frequency, so you have a fast or really fast LFO in LFO1 and a slow or really slow LFO in LFO2.
There is also the excellent Saturator module from the Reaktor Factory Library patched in to the signal mixer section. Mostly because I had some extra room on the mixer panel, but it turned out that I liked the sound of it so I kept it in there.
