basically ive created some patches that are quite heavy on the CPU,

Im using an iMac 2.66 Ghz, 4 GB RAM, 640 GB HDD,

and a Mackie Onyx Satellite sound card/interface

what are my options?, software/hardware, avoiding the need for a new computer,

Thanks for your’e time,

regards,

C

Although this will increase latency.

For example, if you use poly~, spend time optimizing the poly~ voice. If you post the parts of the patches you want to optimize, people can probably point out where the CPU cycles are going (signal rate modulo/divide/multiply, log/exp functions are speed killers, for example).

Use wavetables where possible (instead of calculating values at signal rate).

If you can program C, consider writing portions of patches as C-externals. I’ve had dramatic CPU efficiencies doing so.

unfortunately i dont have any experience with C, although i will look into this,

cheers,
