I am in the throes of my last two lounge jazz gigs on EUB. When that's done I will be going back to original psycho-fusion music, and much of the time that'll entail just bass and drums in the literal sense. Also, as some of you know, I have a bent for DIY cab and preamp building, and I figured a good DSP appliance would be helpful in that regard. Finally, I am putting together a new PA and a speaker management system is mandatory these days as far as I'm concerned. So to kick it off, here's the unit I bought recently: http://www.rane.com/rpm26z.html . I also have a SpeakerPower amp module with another very powerful DSP unit built in, which I've posted about here numerous times. It's more or less the same one used in the Berg IP series, FWIW. Both have their advantages and disadvantages, as usual. I'll concentrate on the Rane unit for the moment though. My conception of a bass rig requires at least three amp channels and three cabs. One channel is dry and full-range at all times, and should be capable of carrying the room by itself in situations where no FOH support is available. The other two channels could be stereo delayed in a spread across the stage (a la Pat Metheny's rig), split for separate processing of highs and lows, used for mixing distortion in the way Amy from Clatter does (with a separate tube guitar amp as one channel, for example), or used in a number of other ways as imagination dictates. Beyond that, I want the ability to send one or two DI feeds to the house that are delayed to the backline if the situation is workable for that. The Rane RPM26z will do allow me to do all those things, plus stereo EFX mixing, a bunch of EQ and compression processing, expression pedal implementation and preset patch switching, and a lot more. Phew...it's been a busy week writing test programs for this thing! I have to say, this has the nicest interface I've yet seen for this sort of application. Imagine routing options something like the Boss GT series units, but with extensive mixing and patching capabilities beyond that. If you hook up a laptop, you can edit in real time and save patches, then just use a small floor switcher and/or a few expression pedals or panel-mounted pots to do continuous control of quite a few parameters, with no computer needed at that point. I'll post a screenshot or two to illustrate what I mean a little later. Questions or comments?
