Hi,

Is it currently only possible to use OSC via the UDP server in Csound 7?

Thanks,
Adam

Hi Adam!

OSC over UDP server is great but the traditional OSClisten should work as well.
Or you had problems?

Hi Tarmo and Victor,

Thanks for your replies. 

Tarmo, trying to use the OSCinit opcode in Csound 7 results in “error: Unable to find opcode with name: OSCinit” so my understanding is that the UDP server is currently the only way to start an OSC server and create a port.

Victor, are there plans to eventually include all the old OSC opcodes in Csound 7, either directly or as part of the optional plugins repository?

I’ve been using the UDP server and really like how much extra OSC functionality it adds. 

The main reason for my question is that I find there is a subtle difference in the way Csound sounds with and without the UDP server. It’s a small enough difference that I sometimes think I’m just imagining it because it sounds good either way and I think this is mostly just a case of me overthinking things.
The UDP server is fantastic and adds a lot of very useful features to Csound so I’m certainly not complaining about its sound quality. However, particularly if I’m working with very short sounds, I subjectively prefer the way Csound sounds without the UDP server so I just wanted to confirm what the current options are for working with OSC.

Thanks,
Adam
