FM3 Turbo: UI lag and intermittent warnings at ~84% CPU

Hi everyone, I’ve recently built a new preset on my FM3 Turbo that is a bit more complex than my usual setup. The CPU usage has climbed to around 84%, but I'm noticing some strange behavior. I don't get a constant CPU overload error; instead, I'm experiencing UI lag, noticeable latency when...

CPU Crashing Way Below 80%

I just got an expression pedal and I've been playing with different applications. Tried attaching it to the Gain controller on the Drive block (using the Klone) so I could play with different gain settings and it makes this weird high-pitched computer sound and locks up so I need to restart it...

More Power

Hi, I've had my axe about 3 months, and just getting to place where I'm creating some custom sweet sounds and using it regularly when I play. I absolutely love the thing; and I know I'm just scratching the surface on the sounds I get. I love the exchange and being able to presets from other...

CPU Usage Chart

Hi guys! I share with you this list of the CPU usage of each block and their types in the AX8. I use it when I mess around with creating presets to get an idea of which type to try when i need to conserve CPU. We can get an idea on which blocks use more CPU than others. This is not an official...

About the CPU Usage..

I guess that the CPU Usage indicates the maximum amount of power needed to run all the blocks in a preset but, if I have a preset with many effects blocks and a high usage percentage but all the blocks deactivated, will the cpu be in idle or on high load? Is the CPU load affected only by the...

Axe-Fx II to AX8 CPU question

I have a axe II right now but I would really like to be able to switch to an Ax8 for portability reasons. I used the usage chart bellow and it says my preset would be at 87% but it seems like the axe8 wouldn't start at 0%. maybe like 10% like the axe II? I also saw that the FW version was 6.01...

Axe FX III CPU/DSP Test!

I loaded up a test patch to test how many blocks the Axe FX III could handle. As you can see, it can handle A LOT.

AX8 Synth Pitch Tracking Tip

Summary: Get your CPU usage as low as possible. While your preset will operate at higher CPU levels, the synth tracking improves as your CPU usage drops - keeping CPU under 75% seemed to give good results and going lower continued to help. Details: I was converting one of Simeon's synth...
