Re: behringer FBQ2496 and midish

Thanks Alexandre.

What finally worked was this:

proc setfilter fid fgain fbw fcoarse ffine {
    ###print {"setfilter args: " $fid " " $fgain " " $fbw " " $fcoarse " 
" $ffine};
    ormev {};
    oaddev {ctl [geto] filter ($fid - 1)};
    oaddev {ctl [geto] bw $fbw};
    oaddev {ctl [geto] gain $fgain};
    oaddev {xctl [geto] freq ($fcoarse * 128 + $ffine) };
    p;
    s;
}
# --- midish configuration
# Unconfigure 'expr' controller
ctlunconf expr;
# Configure controllers
ctlconfx filter 11 nil;
ctlconfx freq 14 nil;
ctlconfx bw 15 nil;
ctlconfx gain 16 nil;
# --- main
# Get MIDI device name from 'aseqdump -l'.
dnew 0 "44:0" wo;
# FBQ uses MIDI channel 16.
onew fbq {0 (16 - 1)};
# -- set list of CCs that will tx 14-bit data on device 0
doxctl 0 {14};

let gain = 0; # 0 = -36 dB is the lowest gain, etc.
let msb = 61;
let bw = 15; # 15 = 1 oct
setfilter 10 $gain $bw $msb  80;
setfilter 11 $gain $bw $msb 112;

> as controller 14 uses the "fine mode", you don't neet to set controller 46. By setting contoller 14 to a value in the 0..16383 range, midish will set the lower bits in controller 46 as well. In your example you need:
