As the saying goes, “I saw this and thought of you”.
Plogue software are planning on launching all of their plugins etc as Linux native apparently in q2 this year which is pretty soon.
Although it doesn’t say whether this is just x86 or arm also.
Frankly, I would not hold my breath for them to release a binary compiled for aarch 64.
ARM processors are generally considered marketable only in the Apple Silicon ballroom: there seems to be quite a bit of prejudice against the computing capabilities is of the Pi, overall, even if in its latest iteration has reached a quad-core 2.x GHz 16 GB RAM and nvme hardware architecture.
I believe that this will change, slowly but ostensibly, in the future. Signs of a growing interest in the Pi5 platform are already showing in the DSP 563 Discord, and other YouTube music tech channels. Fingers crossed then
I am very well aware, as an owner of two of their latest desktop models, about Korg having powered two iterations of the Wavestate, Modwave and Opsix (and possibly the MultiPoly as well) with ensuing generations of the Pi SBC.
But this specific cases presumably exploit a tighter hw-sw integration to achieve higher computational efficiency, as embedded applications running a single synthesiser engine on an extremely tailored OS version, in comparison with more generic aarch LV2 plugins compiled for ARM processors on Raspberry OS.
@hannesmenzel: The Plogue people might be more interested, anyway, in catering their products specifically for Zynthian, which is an embedded system with high computing efficiency.
