Yes, I know, this is years, three decades actually, on from the launch of the SR-16, but here goes. I have an SR-16 and I want to use it as a sound module driven by a sequencer in my DAW (Reaper). In theory I know this is possible as the 1991 video with Craig Anderton says you can use it as an "Expander Module" and so does the SR-16 manual, but neither video nor manual tell you, in detail, how to get it working. I have a Behringer UMC404HD interface which has DIN-Midi in and out/thru as well as a USB B interface to the PC, I also have an X-Touch control surface (CS) which too has DIN Midi in and out/thru as well as USB B to the PC and 2 USB A for devices. The SR-16 itself being vintage (even though I bought it new only a few years ago, yes, I wish I knew then what I know now, but, hey it's here now and I want to use it) has only DIN Midi in and out/thru as well as audio outputs (up to four, I'm using two). I have become fairly familiar with the SR-16 menu's and have been able to get the DAW click to drive the SR-16 or the SR-16 click to drive the DAW (which some have had trouble with), but, that isn't what I want. I have done that connecting the SR-16 via the interface or via the CS. So, although I can get the click to work in either direction either of those ways I can't get the SR-16 to respond, at least not audibly, to the DAW sequencer. I can see the Reaper track VU react apparently based on sequencer input but can't get any sound out, unless I hit the SR-16 pads. I hear those, but, they don't drive Reaper sequencer input and sequencer input doesn't drive them. Connected via the interface or the CS the SR-16 doesn't show up in Reaper's preferences as a midi-device. Maybe it's because I haven't got the settings right in Reaper which are, albeit very flexible and comprehensive looking, also somewhat confusing for a newcomer to life with a DAW (and midi, albeit that I've read a lot about it and been aware of it for 40 years or more). On the other hand maybe it's because I'm having to connect the SR-16 to the PC indirectly either via the interface or via the CS. So I'm getting a Midi DIN to USB cable so that I can connect the SR-16 directly to the PC, maybe that will solve the problem (but, I have to say, I thought that was the point of the interface and the CS that I have having the DIN Connections....). Any suggestions or encouragement welcome.
