For those interested: I took the liberty to package William Brent's [convolve~ ] external and make it available through Deken.
[convolve~ ] does real-time partitioned convolution where the partition size and thus the resulting delay can be set.

P.S.: Didn't have the chance to test on macOS. I'm happy about reports.
