    Teensy based Lexicon Prime Time 93 style delay

    I'm thinking about using teensy audio to mimic the functionality of a 1978 Lexicon Prime Time digital delay. it's a really interesting early digital delay that has the ability to modulate the speed at which it plays the delay buffer, changing the pitch in the process. You can also change the bitrate of the buffer by various increments that will double at each step. When the bitrate/speed of the buffer is at its lowest, the delay is super gnarly and lo-fi. I was thinking about using the granular pitch shift and delay effects to achieve this, but I'm starting to think that I need to write an object that can control the bitrate of the entire audio path so that old feedback is pitch shifted when it's modulated, while new sounds will be at the correct pitch. I would make my dry signal an analog bypass. Here's a demo of the original device. https://www.youtube.com/watch?v=-Pc-dpc_Et8&t=10s They cost an arm and a leg, which is why I'm interested in mimicking its basic functions with teensy. Any advice would be greatly appreciated.

    Delay with modulation is on the audio library wish list. I don't have a time frame for when this (and so many other features) will actually be implemented, but it's definitely planned for the future.

    Yeah, I saw that. I also saw this project and was looking at the code for some inspiration. https://github.com/cutlasses/GlitchDelayV2
    Thanks for your awesome work Paul. I've really been enjoying exploring the things you can do with Teensy. I just made a USB midi/sysex floor controller for my Boss Katana 50 with a teensy LC and a raspberry pi to act as a USB midi host for both devices. (Couldn't get the teensy to recognize Roland gear as a USB host)
