Hi Haven't posted here in a number of ages, as I'm running a very elderly system (Mac OS 8.6, as I'm still using an Opcode Studio 64X MIDI interface with Logic 4.8.1) and haven't had any issues to deal with. If I had the money to seriously upgrade, I wouldn't be using any hardware synths! I do have the last pre-OS X SD and I've just bought a Proteus 2000 on eBay. I am finding that I can't get any thru MIDI from my keyboard for editing sounds and the mini sequencer isn't working with it either. While double-clicking on a preset will bring up the edit window, theree doesn't seem to be any editing going on the the relevant buffer. The only time I can audition a sound from a library is when I import an *.syx file and transmit it to alibrary, in which case I can play it from the keyboard. This stuff hasn't happened with other devices I use - Roland JV1010, Korg 05R/W, Kawai K1. My Proteus OS version is 1.2.1. I have downloaded the latest version from Emu's website, but can't get the eloader application to function on my system. Would upgrading the device's OS help? I might be able to get it to work if I reinstalled OMS temporarily. As there doesn't seem to be a lot of P2K libary about on the net, I was planning to get busy programming -so far not so good, though many of the stock sounds work finew with the tracks I'm currently working on. Any help most appreciated! Tony Thompson
