The Reverbalizer is a hackable electronic multi-effects module for mobile and microcontroller applications. It is hackable in two ways. First, you can adapt it for use in a microcontroller project. Second, you can download or create additional DSP effects and install it on an EEPROM cartridge using an Arduino-based program we developed. It comes with 8 effects in ROM and 8 on the re-programmable cartridge.
The Reverbalizer uses the FV-1 DSP chip from Spin Semiconductor. The chip was designed by Alesis founder Keith Barr and appears in many effects units like the Z-DSP.
The built-in effects are:
- Pitch shift
- Test (straight through)
- Reverb 1
- Reverb 2
Here are a few sound samples made using the output Bytebeat Shufflebox for Arduino going in to the Reverbalizer.
