The Roland (or Edirol) SC-8820 is worth a look. First, the MSRP is below $450 and weights less than 1 pound. It has 32MB of compressed sounds which Roland considers equivalent to 64MB. The module is GM2 compatible.
This is a USB device. The USB interface provides power to the SC-8820 and serves as a two-way midi connection. The SC-8820 also has a midi in and a midi out.
I believe the midi in and the USB are merged.
I cannot tell from the Edirol website what is the best way to configure a JammerLive system with the SC-8820. It would be nice if a single midi cable from the controller to the module were all that was needed other than a USB cable from the computer to the module. If anyone has a chance to check this configuration out, please report.
For more connectivity at a higher price, the Edirol SC-8850 is worth a look. Same sounds, but two midi ins in addition to USB.
