Odd TTS-1 Crash – No Dump

I have a template with 1 instrument all outputs mono, and a slew of aux tracks & FXs, using optional sends for FX signal paths & various configurations for 5.1 hard out targets, and NO busses... After adding TTS-1 (1st Stereo out) set to channel 10 for percussion, on playing any TTS-1 note CB crashes with no dump. If first, I delete the 1 instrument, then add the TTS-1 as before followed by adding back the 1 instrument configured as before deletion, it all works as expected, no

@msmcleod Thanks, that totally makes sense, explains why inserting 1st worked for me 😁 Since I use it as a substitute for the GS Wavetable percussion, last night I found an alternative, SF2s found at this link: https://musical-artifacts.com/artifacts/1549 and used "sfZed09" sfz format editor at this link: http://steveholt.drealm.info/sfZed.html, to convert the SF2 percussion to an SFZ then loaded it into Rapture Pro, which eliminates TTS-1 issues & my ol' SF player's not reliable, All the
