Amazing, hope you get a chance to work on your project further and post updates
You were able to load more than 16 raw samples in the flash memory chip? That's amazing. Can't wait for final end result. Good luck! I do understand how projects can get into a limbo specially when you have kids.

Yeah, I wish i had more time. I made the samples mono @ 44khz 16bit and squeezed them in!!
Excellent video. Keep it up!

Hey, has this project gotten any farther I'm the last few years? I've got a Teensy 3.2/audio board and I'd love to build this!!

No I’m afraid not; I had proven the concept and since it was such a massive undertaking of code I’ve not really had the juice for it. I’d be happy to share my code to here but it would need updating. I know that the synth features and effects available are significantly more advanced now - like reverb and such.
Hey man! Nice video! I'm trying to make a device where I wanna alter the speed/pitch of samples (resample?), but I'm not able to do this without a lot of artefacts in the audio.... Do you have any tips on how to do this/ where I can learn to do this? Would be greatly appreciated!
This is an awesome project! I make hip hop and am working on a drum machine/synth with teensy and would love to connect with you. You really about made an MPC from scratch bro that's crazy. Do you have any socials or anywhere you talk about how you work on this stuff?

Also - checkout the phatfingaz project - its the next logical step for the buttons with RGB backlighting which worked really well - that was only a midi controller (bigger version of midi fighter with full size buttons) - and with RGB you can have cool different modes - one of them was a transport contorl for pause play rec stop and mute/unmute of multiple channels etc. Honestly the next step for any drum machine or MPC type product is an RGB backlit MPC pad PCB with neopixels in it. That being modular and usable in any arduino based project while being compatible with genuine MPC pads and membranes. I'm surprised noone has done it yet.....
I love the Mad Zach!

wow. impressive. please please please open source the code! how is sampling working?

github.com/Pensive/Beats-by-Teensy :) Sampling is all handled by the Teensy audio library, samples are loaded onto a flash chip (slowly!) then played back really really fast ;) It's surprisingly easy...
Swing i think, or maybe its called groove

Can you please send me the link where you bought those push buttons?
This is brilliant! I want to do a similar project, way easier than this but i would really like an audio input to sample directly from the machine. Do you think is possible?

simone iacoponi yes - to a limited extent. Teensy audio can record to SDcard live at 44khz and playback, and if you need to this could be burnt to a faster memory chip in small chunks for high performance sampling across multiple tracks. It wouldn’t be easy - that’s an advanced project with a fair bit of work involved - but it can be done and with a bit of help from very clever people in the teensy-verse you could optimise the process to make it really effective. The newer teensy boards are really powerful and the libraries are amazing - you could do some pretty cool stuff.

@@StuffAboutStuff buying a teensy 4.0 right now. I just need it to sample on one track at a time, even only 5/6 seconds mono, trim the start and end point and maybe put an effect on top of that. How is your project going anyway? You should update us!

simone iacoponi this project has unfortunately not gone very far, I’ve moved on to other things at the moment. Your easiest first take would be to get a really good SDCard and you can record and sample from that. For basic stuff that would work fine. You might be limited to 5 or 6 samples at a time, maybe more on a teensy 4 - you might need to drop the frequency rate for a proof of concept if you need more concurrent samples than that.

Long since discontinued now unfortunately - it was bought from adafruit originally. I would absolutely recommend a capacitive touchscreen these days. I’m using an M5Stack core2 on my latest project and with the m5 button library it’s rather impressive.....

very nice! Did you use the memory chip on the audio board or is that straight from SD card?

I soldered the audio chip on and loaded most of the samples on that to save the cpu for the long term goal. I managed 5 or 6 streams from sdcard concurrently at 44khz if I recall, but cpu was getting battered :D I’ll upgrade it to a Teensy 3.5 soon ;)

consider the 3.6 - it has significantly more float performance than 3.5 (which is actually pretty close to the 3.2)

Jan Kruse I know but it’s 5v tolerant so it’s a direct drop in. That and I have 5 of the things. I do have a 3.6 too though. Maybe! :-)

Boi Mesa it's written in a subset of c++ called Wiring - the arduino language. The audio board is a daughter board for the Teensy range of arduino compatible microcontrollers. So it's all embedded code - there's no OS.
