Make DSP Instruments with Embeded Modular Synths using Axoloti

Axoloti Community / Mailing Lists / Google Groups

 

 

Axoloti helps digital luthiers like me:  I have been designing DSP music instruments using the STM32F4 chip for several years.  It's time-consuming to hand-write DSP code, but also extremely rewarding because the chip is powerful, small, and draws little power, making it great for making embedded instruments.  Axoloti, with its STM32F7 sounds much better than any Arduino and boots faster than a Raspberry Pi.  I'm glad many people have supported this project.  I am personally using it to make DSP-based Music Instruments for musicians.  Please contact me if you are a musician and would like me to design an instrument for you using the Axoloti.

Why is this so Important?

 

Modular Synthesizer Editing - Digital Modulars are much faster and easier to use than writing DSP code.  You don't have to be a programmer to update the sound of your instrument - although you would still benefit from the assistance of a digital luthier.  It's also easier to share patches than analog modulars.  Your digital luthier can email you patch updates while you're on tour!

DSP - Digital Signal Processing gives instrument designers incredible power and freedom to make wonderful instruments custom-suited to performers' needs.  It lets them continuously update the sound.

STM32F4 - This is the chip used in the AxolotiI've been teaching people how to use this chip for years now.  It's an incredible intersection of lots of CPU power with low electrical power.  I've been sharing information on this website pointing people toward DSP instruments made with it.  Now I'm happy to applaud the choice of CPU/microcontroller used in this device.  It has a floating-point unit and is clocked at 168 MHz.  The next step up is a Raspberry Pi, but the STM32F4 costs half as much, boots instantly, is smaller and uses less power. 

Open Source - The designer/inventor behind this crowd funding campaign has chosen to make the project open source, so many more digital instrument designers in the future (like me!) will benefit from it.

Inexpensive - So far this costs about $100 (it actually ships from Belgium!).  You might think that's more than, say, a Raspberry Pi, but keep in mind, this hardware is specifically designed to be used as a digital music instrument.  It has onboard MIDI, headphone and 1/4" jacks.  They're not just optional peripherals.  It also has an SD slot and a USB jack.  That's a good deal for you money.

 

Conclusion

I highly recommend that everyone contribute to this Indiegogo campaign.  The amount of beautiful new electronic instruments it will enable is almost too gorgeous for me to imagine - picture a ferris wheel through a kaleidoscope.  As I mentiond before, I've been building DSP-Based instruments with similar hardware for about a year now and others have been doing the same with the stm32f4 chip.  We've been writing DSP code by hand, but this project will make it soooo much easier for us and therefore help us get brilliant instruments into the hands of musicians.
