Rack tremolo idea

I’ve been thinking about building a new version of the tremolo I mentioned in the previous post. This will be a very versatile tremolo/volume controller in a 1U 19″ rack enclosure.

Some of the features are:

  • Stereo in & out
  • Two tremoloes (one of which can pan between left and right)
  • Tap tempo
  • MIDI PC’s and CC’s
  • Multiple in- and outputs so the tremolo can be placed before or after the preamp
  • Speed, volume, depth etc. can be controlled real-time through MIDI CC’s or expression pedal
  • Various waves: sine, triangle, ramp up/down, square, patterns, random…

This will be a huge improvement on the pedal tremolo but it’s also a very big project. At the moment there are only ideas, some schematics, a bit of software pseudo-code and an idea about the design:

Next week I’ll probably start with the power supply, the PWM filters and the voltage-controlled amplifiers.

    I wonder how you went with this. You reckon it would be possible to operate remotely via bluetooth, wifi, or IR. If you had a bunch of presets – the ability to scroll through or key in a number (like tv remote) would be handy for gigs or studio. your vid of the trem ped sounded nice,,,

    Hi steve,
    Haven’t done anything yet. I still have the idea to build an advanced tremolo, although in a pedal form. Controlling it through IR would be the simplest solution, but why would you? In most studio’s and live front-of-houses you would probably stand right next to it :)
