Hopefully i can start working on the software next week. I hadn't had the chance to work on this since 1 month. Additionally I only used floating point arithmetic so far, with C#

Ian using this in my apps, was easy to port and sounds very nice.

Awesome, the dev of my legendary OP-1 are back with Arm M4 powered devices: http://www.theverge.com/2015/1/22/7868157/teenage-engineering-pocket-operator-synthesizers

Hi Roel, i stopped working on the idea to prefetch data and will go the SPI Flash route.

Paul, i totally agree with you. I currently do that Kind of adress + length for reading from sdcard in my drum computer prototype. If we focus on streams, simplicity and performance, index and length is sufficient for me, as i know what kind of data I've written and want i need to read.

Thats why i posted spiffs library.

I like the discussion which is going on :-) I remeber something like lifetime management on flash memory, does that apply to our table/library as well? - http://en.wikipedia.org/wiki/Wear_leveling - https://github.com/pellepl/spiffs Spiffs looks really nice and tested. It seems to support...

I would buy such a board as well. Currently I have hard times to find someone selling those chips in Germany, @Frank where do you have it from, Digikey? I think the WSON8 chips can be soldered as well, at least i managed it some ages ago :-)

This is really nice Frank, Danke. I wonder if it is possible to use a different chip of that family with more capacity, shouldnt be a problem if i understood the specs correctly. W25Q128FV W25Q256FV maybe?

Update: HW: - Display running - Knobs and buttons do colormap now - Trellis running SW: -Have to learn a bit more on audio effects and audio streaming (the engine must be pulling the bytes, not pushing, otherwise cpu is overloaded too much)

Update, sorry that i am using this thread as a kind of blog/history for myself. Knobs + Encoders + 1,8": Audioports: USB: Alps + OKW Knobs (colors do not match with knobs so far): Closed battery compartment: Openend battery compartment:

HW update :-) The idea was to laser everything into my case directly, but the ABS material started burning while lasering it. So i used a CNC to gut the front out of my case ;-( and relasered everything into plexi. BOM: - Teensy 3.1 - Teensy Audio Board - 1,8" from Adafruit - Trellis from...

Hi, I think this will be doable, maybe not 64 poly. Today i hocked up an trellis on my Board, works quite well. Sure its not an mpc, but its a lot of fun. �� Im interested with what you will come up. http://forum.pjrc.com/threads/26861-Project-Teensy-3-1-AudioBoard-Sequencer Andi

Hi all, Yesterday I visited a iot hackathon here in Nuremberg. I ordered a teensy and an audioboard the week before but had no chance to get into it. Nevertheless I got something working after 7 hours, not too impressive but I won the competition.�� 32 step sequencer Recording...
