Automation of individual piano parameters with Reaper DAW allows for online rendering only.
Offline Rendering crashes Reaper if individual piano parameters of Pianoteq are continuously changed via automation.
Is this a bug in Pianoteq? This is costing me a lot of time.
I tried a little more. For example, if I automate "Strike Point" by LFO in Reaper and no other Pianoteq parameters, it works. But if I e.g. automate "Strike Point" and "Blooming Energy" with LFOs each, this bug will occur: "not rendering, ETA infinity" -> rendering window freezes
Then only online rendering works. But this is too slow for me.
I tried it with the latest Pianoteq 6 Pro version (tested with the VST3 and VST version) and the latest Reaper version.
UPDATE: It does not seem to crash completely in offline rendering mode, but to render extremely slow (90x more time than the rendering process takes if I automate only one parameter via LFO). After a longer time the rendering window also refreshes itself and looks normal (but freezed).
I contacted support about this issue, and the suggestion was to use fewer automation points.
In Bitwig Studio I was able to achieve this by quantising the automation
The top modulator modulates the second one (red arrow) which quantises its input to eight steps instead of continuously.
This sounds the same to my ears and renders faster than realtime.
