Does anyone know if the playback delays have got significantly longer with the 64-bit version of Sonar and the Transient Shaper TS-64 Plug-in and/or Session Drummer 3 64-bit? (or with Win 8 versus Win 7?) Or are there problems with the reported latency of SD3 and/or TS-64?
The reason I ask is that since moving to Win 8 and changing to Sonar 64-bit (X1d) all songs (even simple single track ones) which use a Midi track to drive Session Drummer in real time and have a Transient Shaper TS-64 effect applied have become completely unplayable - drum beats frequently missing or badly out of time. (The other tracks play fine and stay in time). The only way I've found to rescue the songs is to freeze the Session Drummer track; TS-64 applied to the frozen audio output via a bus works fine. So I've lost the ability I used to have to make changes to the drum track during mixing, despite having a much more powerful system than in Win 7 with 32-bit Sonar. It only seems to be TS-64 which gives the problem - other plug-ins are fine.
Setup is Sonar X1d 64bit running on an i5-3570K, 16GB, 256GBSSD. Windows 8. Audio interface if a MOTU828 MKII Driver version 4.0.5.5333. Problem is the same in both ASIO and WDM driver modes. Buffer size adjustments seem to make no difference.
(I've also reproduced the problem on a laptop running Sonar X1d 64-bit Windows 8 and a Focusrite VRM interface)
