On the RaspberryPi website the question about the absence of audio-input was answered recently:<br><br>There are no inbuilt Audio ADC’s so there would be a cost adder –
everyone was sat on my head to get costs down. They can be easily added
via the GPIO.<br><br>So, still a possibility in an embedded openstomp-ish device.<br><br><br><br><br><div class="gmail_quote">On Sun, Mar 4, 2012 at 6:26 PM, dreamer <span dir="ltr"><<a href="mailto:dreamer@puikheid.nl">dreamer@puikheid.nl</a>></span> wrote:<br>

on the OMAP3530.<br>
Which has audio-in/out and gpio on a single plug.<br>

Combining that with a stompbox that holds, for instance, an msp430<br>
(launchpad, by ti) with an lcd-screen and some nobs would make for a<br>
very nice interface :)<br>
<br>
Still looking in to compiling for their OS.<br>
The pandora is then again a very small niche, hence I was reflecting<br>
on the current interest towards the RasPi.<br>
However I didn't realize this device doesn't have line-in, so that<br>
indeed is a little discouraging.<br>
