But here is an FM glitcher using d-scale and Tonalatonal, I patch I found on list a few years ago that is RIPE for rjDJ-ness Maybe you can look at these and help me make em a little more spiffy, or at very least get tonal working!
Okay, that's a bit of tedious work. but doable. The patches only use [sort], which you can replace by [list-sort] with [list-rdrip] from the [list]-abstractions. They only use [sort 1] which is ascending sort i.e. a naked [list-sort].
A bit more tricky to replace are the expr-constructs used. Fortunatly [d-scale] is only used as [d-scale -1 1 1 100 100]. This is sufficiently similar to [m_scale -1 1 1 100 dB] from the rj-library, so I'd just use that.
Another expression used several times is this:
expr~ if ($v1 == 0, 0, (if ($v1 < 0, -1, 1)))
This is a signum function for signals. You can replace this with the sgn~.pd from the "purepd" collection in CVS/Pd-extended. Make sure to also get the lt~.pd and gt~.pd abstractions. Alternatively you can also get away with this:
[inlet~]
|
| [abs~]
| |
[/~]
|
[outlet~]
I.e. divide a signal by its absolute value. Division of 0/0 in Pd here gives 0 again, so you're cheating okay around this exceptional case.
The other expr-expression just require some work to explode them into normal math objects. You will gain a bit of execution speed by this, as expr is a bit slower than exploded math.
