The drummer in my band has an Alesis e-kit (DM10 mkii Pro) which he uses for rehearsals and recording. We record into Cubase 12 Pro and usually use a drum VST such as Steve Slater Drums. We have the e-kit connected to a Windows 10 laptop via USB Midi. Everything else we record is connected to the laptop via a Behringer XR18 mixer/interface.
Recently something odd has occurred - the e-kit triggers the drum sounds from Steven Slater Drums perfectly fine when we’re not recording. But as soon as we hit ‘record’ in Cubase, sometimes there are a few issues where the drum sounds won’t trigger properly, especially during faster drum fills. Any ideas what is going on here, and how we can solve it?
I’ve got the buffer setting in Cubase set to 128 samples. I lowered it to 16 samples, and it was maybe a bit better but still not always triggering the drums 100% when recording. At 8 samples, the sound started to sound corrupted, so I had to make it higher.
Generally I record at 24 bit / 48kHz. The input latency in Cubase is around 4.1 ms, and the output latency is around 4.5 ms.
The laptop is a pretty decent speed and spec, so I don’t think it’s the speed of the computer that’s causing these issues. But maybe it could be, I don’t know? We still get issues triggering during recording the e-kit even in a fresh Cubase project with just 1 track, so it can’t be caused by having too many tracks in a project taking up too much CPU power. The specs of the laptop are as follows btw:
HP Envy Beats edition with Windows 10 Home (version 22H2)
Processor: Intel Core i7 4700MQ CPU @ 2.40 GHz 2.40
The computer has 2 disc drives - one is SSD (222 with 13.3GB currently free), the other is HDD (931GB with 841GB currently free).
I had to install Cubase Pro and Steven Slater Drums to the HDD drive as the other drive was running out of space. Do you think it makes any difference in speed of triggering and latency with software installed on the HDD drive as opposed to the SSD drive? I don’t get any other problems with latency on the HDD drive - audio, keyboard VSTs etc all work fine and with decent speed.
