Hi Julian,

To make this work you can modify the partial.pd abstraction to  
receive the frequency message as a signal. e.g. replace this bit:


      [r frequency]
|    |
[*  ]
|
[+  $4]
|

with this:

        [r~ frequency]
|      |
[*~  ]
|
[+~  $4]
|


then send something like

[72, 72.4 15(
|
[line~]
|
[mtof~]
|
[s~ frequency]


Does that make sense, dad?

congratulations,
Collin
