ForumsSoftware ← Aalto and VE Pro


I just purchased aalto 1.1. I'm excited to see a piece of software that deals with electronic sounds in this way.

I took electronic music classes from Mort Subotnick at CalArts during the 1976-77 school year, when he was working with a room full of Buchla modules, and I used small Buchla modules for comp. assignments. This approach reminds me a lot of the way the hardware worked.

Anyway, I've been trying out aalto using VE Pro (32 bit version), since VE Pro understands AU. I'm using Pro Tools 9 for the sequencer, and I'm getting the sounds working just fine.

I have noticed, though, that aalto is always acting like it's trying to run, or loop, or something (fan increases now and then) when I have patches loaded. No sound looping, just the computer's fan increasing, as if something's trying to use more CPU.

Nevertheless, I'm happy to invest in your software!

Hello again.

I just tried Aalto with Logic 9, and it seems to be less intrusive on the CPU. I know that VE Pro itself uses a good amount of CPU energy just sitting there.


Hi Dennis,

Thanks for writing and sharing some of your history! I am very happy that some Buchla users have responded well to Aalto, and find it can complement a hardware setup.

Aalto does use CPU when it's not playing notes. The free-running oscillators are always going so that you can just turn up the gate level, for example, to make a drone. I will be doing some optimizations to get the CPU use down while keeping the benefits of this setup.

Ya, Randy. Now I remember how the real Buchla modules work. Makes perfect sense! No problem!
