[Cs-dev] Filters with a-rate parameters

Subject[Cs-dev] Filters with a-rate parameters
I have reached a small hiatus.

At present the following can all take a or k rate parameters
  
areson
atone
atonx
butterbp
butterbr
butterhp
butterlp
fofilter
lowpass2
lowres
lowresx
lpf18
moogladder
reson
resonr
resonx
resonz
statevar
svfilter
tone
tonex

Some others (moogvcf, rezzy, tbvcf) already took xvars

The leaves three filters that are much harder to change -- cfilt, resony
and vlowres -- which will take some time to adapt.

I ma have missed some other filters which if so I would like to know.

I think the manual pages are also updated to reflect this change.  I
have done basic testing of all these in the sense that the manual
examples all run, and they run with the first parameter (usually
frequency) at a-rate.  I have not tested things like a-rate bandwidth.

I would appreciate feedback.

Thank you very much! A thankless task by the looks of it.

Beyond filters, I guess we can look at signal generators that are not yet fully a-rate capable. I guess this is a long haul.

This is great stuff John. Having audio rate control for all filters is a serious upgrade for Csound. Thanks.

Indeed - I have only a rough idea of how much work is involved in doing
this.  It will enable many interesting and satisfying musical explorations.

Thanks John!

BTW, I just joined this list.  I am hoping to do at least some
occasional Csound music with V6.01 and beyond, after concentrating on
other things since the late 1990s.

Agreed that this is a big deal; really looking forward to updating my
Csound code to use this.  I've been using the mode opcode a fair
amount, so would second Joachim's mention of that one.

Also glad to see Robin here: welcome back!
