Hi everyone!
Has anybody tried this yet:

I'm going to give it a try soon, looks like fun!
Cheers, graham

I have a WTPA. It's pretty cool, very easy to build. The interface is kinda tricky, but you can take a sample and lower it's bitrate, reverse it, mix two samples randomly, and some other stuff. I saw the guy who designed it (Todd Bailey) speak at bent fest. He's a cool guy and definitely deserves the support too.

I quite fancied designing something like this but I've been beaten to it ;-)
Oh well, guess I have to buy one then.

He's nearly sold the first run of kits, they went like hot cakes. He's working on the next board revision for the next batch; it will incorporate different SRAM that can have battery backup of the samples when the power is switched off (the SRAM he is presently using can do this too but the chips are high drain standby current ones, and would go through a backup battery in a few days. The new SRAM he wants to use are ultra low drain and should keep their samples for a year or so, on a coin battery type Lithium battery.
You could still probably convert your old v1 board to the new SRAM just by wiring the appropriate SRAM board terminals to an IC socket that fits the new SRAM, then add a battery and backflow diode to prevent the backup battery being charged while the sampler is switched on. The new boards will be able to drop a socket into the board (the present one uses surface mount SRAM soldered directly to the board) and make soldering and troubleshooting a lot easier.
