Following up from the thread on the Audiobus forums. Yes, Cubasis is relatively stable if I don’t use any instruments or effects. Following your steps above a have a relatively usable DAW without any of the sounds I want to make.
From the other thread…
The project that I was trying to work on had 3 Classic Machines tracks and two AUv3 instruments (Pure Acid and DRC - both chosen as being among the least resource hungry and rock solid in AUM / Beatmaker 3). DRC was using Blackhole and Pumphouse inserts, but I froze that straight away. Two of my classic machines tracks had to be frozen too, one using UltraTap and the other using Replicant 2. At the point that I gave up, it was just three frozen audio tracks, one Classic Machines track and one Pure Acid track. No effects.
This evening I recreated the project in Beatmaker 3, but with DigiStix standing in for Classic Machines, and with all the AUv3 instruments and effects in place, nothing frozen out as samples. Even when I kept on layering extra effects that weren’t even in the original C3 project, Beatmaker’s CPU meter jumped around between 30 and 52% and shows RAM usage of 256kb
The same Project setup in AUM with Xequence 2 as a midi controller, and utilising multi-out and AU sidechaining to RoughRider 3 - AUM’s DSP meter never went above half way.
On top of that, both Beatmaker and AUM remain responsive with zero UI lag.
Also from the other thread…
if the thing doesn’t work with 3 audio tracks, one Classic Machines and one AUv3 then the thing doesn’t work as a DAW. I don’t think I have any use for it if it can’t use AUv3s.
I’m about to try opening the project in Cubasis 3 again to see what the meters show, but hitting submit first in case it takes the whole iPad down again.
