Demo of the HISE library I'm currently working on

The debug logger thinks I'm on Windows 8, I'm actually on Windows 10 - is this important?

Christoph Hart

Not really - I am calling a standard JUCE function to get the OS version so it might be something wrong there. Shouldn't be too much of a problem though

d.healey

Ok cool. The CPU readout seems all wacky in the latest build

I'm getting some performance warning messages from the debug logger with my staccatos. I don't have much scripting going on there so I'm going to isolate the sample to see what's happening

Update: I'm exceeding the voice limit when playing a lot of staccatos. So that's ok, not a scripting issue :)

Christoph Hart

Can you post the debug log? If you post it here, it should get formatted correctly (it's using markdown syntax).

RE the CPU meter, I think I fixed that meanwhile, but there are a lot of changes that I haven't commited yet (new colour schemes, faster graphic rendering on OSX, more logging features), so I have to clean up a bit before commiting.

That looks OK. The performance warnings are slightly above the threshhold so it's nothing unexpected.

Are you using any filters? They are currently the most inefficient part of HISE.

d.healey

No filters, I have 2 LFOs for vibrato, a few CC modulators, some envelopes, and a sample start modulator. I'm also using a simple gain for each channel.

Christoph Hart

Alright. I'll wait for your project files then I can hook up a real profiler to see if there is some unnecessary overhead somewhere.

Lindon

Well done lads, nice to see optimisation getting some air space.

d.healey

Private message with project download link sent. The new UI colour scheme looks good.

d.healey

I noticed that LFOs seem to make quite an impact on CPU

Christoph Hart

Yeah, I recommend using LFOs as global modulators once and just grab their value at the various location (it seems like you have duplicated the LFO for gain & pitch vibrato, which also increases the complexity and kills the workflow - you'll need to change it at two locations every time).

I also noticed you are using a lot of MIDI controllers for a lot of crossfading stuff. There is a neat little trick with global modulators and that is to use a table on the receiving modulator:

I'll have to make more tests but this approach looks like it is faster (because it doesn't have to process the MIDI events and apply the smoothing filter for every module, but only once in the global modulator). But it also looks a bit cleaner to me (plus you can change the "responsiveness of each MIDI controller by changing the table in the global modulator pretty easily)

d.healey

Aha that looks interesting, thanks, I shall experiment.

d.healey

Another library I'm building - woodwinds again :) Just need to implement a preset system for it

I think I understand why you need the textColour property :)
