I'm trying to figure out the correct way to send control data to the svf plug
following how [plugin~] is supposed to work:
the message is: "port symbol:direction symbol:type symbol:name float:lowerlimit float:upperlimit"
with symbol:direction being either "in" or "out" with symbol:type being "control" or "audio" with symbol:name being the name of the port (e.g. "Amplitude random (%)")
and lower/upperlimit define the valid range of the value.
for controlling, you use "control symbol:name float:value"
symbol:name is not case-sensitive, and it tries to find a simple match. e.g. "Amplitude random (%)" can be controlled with "amp" or "AMPLItude" or "Amplitude random (%)". it will take the first port that matches, so if you have parameters "FrequencyUpper" and "FrequencyLower", then "freq" will match "FrequencyUpper", in order to control the other param you have to use at least "frequencyl"
in the terminal 'analyseplugin' for svf reveals this:
Plugin Name: "State Variable Filter" Plugin Label: "svf" Plugin Unique ID: 1214 Maker: "Steve Harris steve@plugin.org.uk" Copyright: "GPL" Must Run Real-Time: No Has activate() Function: Yes Has deativate() Function: No Has run_adding() Function: Yes Environment: Normal or Hard Real-Time Ports: "Input" input, audio, -1 to 1 "Output" output, audio, -1 to 1 "Filter type (0=none, 1=LP, 2=HP, 3=BP, 4=BR, 5=AP)" input, control, 0 to 5, default 0, integer "Filter freq" input, control, 0 to 6000, default 440 "Filter Q" input, control, 0 to 1, default 0.25 "Filter resonance" input, control, 0 to 1, default 0
I'm having trouble figuring out what exactly to send the plug I tried sending 'type' 'filter_type' filtertype' and other combinations for "Filter type" but it doesn't seem to like anything I try
*error: plugin~: plugin doesn't have a control input port named "type"*
ditto on 'Q' and 'resonance' although 'filter' seems to be accepted for "Filter_freq"
can you point me to where in the code I might find out the correct syntax for a particular LADSPA plug?

Hi Kim,
try:
[0
|
[control #n $1(
|
[plugin~ svf]
where n is the number of the parameter (so #1 or #2 or #3 ..etc)

thanks Tim I seem to remember either the DSSI~ or LADSPA~ object using this syntax I'll see if this also works with the plugin~ external thanks for your help!! :)

works like a charm! thanks again! - for the svf plug at least
does anyone know if the use of [control #n $1] is global? i.e. works across all LADSPA plugs hosted by [plugin~] before I cause more RSI by testing a bunch of them? ;)

As far as I know, it is global. It has always worked for me.
