Is the problem that _phase and _omega get reloaded from
memory every time they're used?
Would it not work to declare process() as:
float process() __restrict
{ ... }
Thus telling the compiler that `this` is not an alias when
process() is called.
Or perhaps:
int process( jack_nframes_t nframes, void *arg )
{
int i;
float * __restrict__ buf = (float *) jack_port_get_buffer( out_port, nframes );
Ramp * __restrict__ o = &osc_block;
for( i=0; i<nframes; i++ ) {
buf[i] = osc_block.process();
Change to:
buf[i] = o->process();
