I have almost the same settings and about 15 Tracks (Audio-Only, no FX anymore) to see if i can use it again. Actually i’ve added a new track including SD3 with all sends to single channels and now it works. It seems like there has been some issues in the instance-settings or something track-related i didn’t notice. By no i can use it without lags for about half an hour. I’m not sure what has happened or what did change, because i tried that before on the same track to keep the sends and routings.

After adding completely new tracks and route them how i need/like it, it seems to be fine. Maybe i just had some tweaks which had not been as good as i thought that i do not remember.

Nevertheless thanks for your attempt to help and reproduce it! I’ll keep checking the settings and try to find out more if i can see this behaviour again in the future.

Best regards,
Ian

So and again.. It appeared over time but is not reproducable definitely. It seems like the project itself has been blown up to more than 10000 bars inside SD3. Default its about a few hundred. I’ve noticed some serious issues with the MIDI-Song-Editor which holds the MIDI-Blocks. The scrollbar with the preview inside has shrunk and is therefore not usable anymore. You can’t navigate through your song. Maybe SD3 has problems with too large projects including a few thousand bars. I didn’t do anything special. Is it possible that reaper sends invalid project-length-data to SD3 so it assumes the project as very big and therefore is not able to display that many bars properly? Maybe it lags while updating the view and it’s just too much data.

Record Arm does not change anything for me.

Hi John,

sorry for the very late response but yes, at that time resetting the bars to 200 or at least a lower value fixed the problem!

Now after some trouble with my computer(s) and switching to a brand new Macbook Pro 15 (2019) Model i’m observing new lagging behaviour. It looks like it’s fine in standalone mode but the whole Superior Drummer interface and the DAW interface starts lagging (grid editor, drums, mixer, DAW-Meters….) when used in a DAW (Reaper, Ableton Live 10). It looks like it doesn’t change when using either AU or VST. This does only happen as long as the Superior Drummer Window is open. Audio isn’t affected in any way from this behaviour. It’s just the whole interface. So when programming MIDI oder Editing something in the SD-Mixer isn’t very nice to do.. I’m not sure, if someone else can reproduce this behaviour. I’m currently running macOS Mojave 10.14.6.

Are there some known issues or any settings/fixes i’ve not seen yet?

Best regards,
Smokehead

Hi, it’s me again.

After working for some time using multiple monitors i’ve been forced to use the Macbooks display without aditional monitors. Then i’ve noticed that it’s still lagging massiveley as well in Ableton Live and Reaper. It seems like it’s not working that well with some scaling/rendering issues. It is slightly better when using the smallest scale and window size but it’s still lagging when editing MIDI in the Grid Editor or when ‘watching’ the drums playing. The worst thing i can do is selecting an instrument with the cursor. Then it’s about half a second until it’s highlighted (blue). Sound is almost there immediately. It doesn’t get better when using high buffer sizes and low sample rates which results in very bad latencies.

I’m still using macOS Mojave. I don’t want to update to Catalina yet.

Still hoping for news..

Best regards,
