It is with great joy I am able to present to you: our dearest little newborn, The MicroWaveSampler.
An Arduino/Adafruit WaveShield-based 'Lo-Fi' Sampler with 16-step sequencer, preset function and external clock.
A project between my best g33k-buddy Carl @ DimSos and I, which has been underway for a year.
We chose to call it MicroWaveSampler because it's a Microprocessor-driven Wave-sound Sampler.

Go to Dogenigt.com: The MicroWaveSampler for info and Demo!

Congratulations on the birth of your new baby!! I love the baby blue eye and the how it tells you when its ready. It looks like it has a lot of functionality, which is nice for a new born!!!

Cool. Congrats
Does it have also an output for clock?
A row of 16 leds would be nice. It may be a personal thing, but i feel lcd screens are anti-musical... for presets and configuration options its good though.
Did you measure the precision of the clock? With an oscilloscope or anything? Just wondering because i'm developing a sequencer as well, midi though.

No, no output for the clock - I plan to use my Clock Box to sync my modules and no pins available for any digital I/O's, this atmega328 chip is absolutely pushed to the limits, every pin is used. Smile

And yeah, 16 LED's is a priority for version 2, again it's the pin-problem which made it impossible to add and the whole idea about having 16 characters a row on the LCD made it an obvious implementation to just show everything sequencer on the screen. It's not meant as an ideal sampler/sequencer, it surely lacks a lot of features - it was a personal task to see if it was possible to build a sample-player from the Wave Shield with limited means and experience.

Thanks for watching!

For the future you may want to check the shifter 74hc595. It's pretty easy to use, you can daisy chain them too. By using 3 digital you can expand them to 8 digital out, 16, 32, 64 or whatever. You can use one for the lcd display, and other two for the 16 leds. There's a library too...

Thanks man, I am aware of that one - that will be the way to go when you are fortunate to have 3 I/O's at hand Wink
It's the plan in the next version for sure.

EDIT: Oh yeah, I see what you mean now. Of course there would be pins free if I use the shift register for the LCD.

well i think its pretty cool..if yuo come up with a PCB or DIY type (read: lo budget) way to sell it, id buy it. The lower it costs, the more id buy--but i like the simplicity and dedicated stuff. I hate menus and whatnot. Ideally everything would just require a power switch.
