Hey there

I have the following SynthDef:

```
(
SynthDef(\saw, {
arg freq=440,out=0;
var snd, fft, key, feedb;
feedb = LocalIn.ar(2);
snd = LFSaw.ar(freq+LFDNoise3.ar(3,0.7),mul:1).tanh;
snd = snd+(feedb*0.5);
LocalOut.ar(snd);
snd = FreeVerb.ar(snd,0.4,1);
fft = FFT(LocalBuf(4096), snd);
key = KeyTrack.kr(fft);
Out.ar(out,snd);
}).add
)
```

And I want to use this with a MIDI Keyboard:

```
MIDIClient.init;
MIDIIn.connectAll;
(
var notes, on, off;
notes = Array.newClear(128);
on = MIDIFunc.noteOn({ arg veloc, num, chan, src;
notes[num] = Synth(\saw, [\freq, num.midicps]);
});
off = MIDIFunc.noteOff({ arg veloc, num, chan, src;
notes[num].release;
});
)
```

I would like to transpose this Synth one semitone higher. I tried something like “num=num+1” or “(num+1).midicps” but this isn’t doing what I am looking for and I don’t have any ideas left.

Thanks!
