Hi, First of all: thanks for chuck. I'm having a lot of fun with it. Followed by: Hello list. I've just joined. And finally: I may be doing something stupid, but I can't get chuck to connect to midi ports. I realised after a while that it had to connect to an existing port, and wouldn't make a port to connect to later, so I fired up vkeybd. aconnect -i shows: [snippet] client 128: 'Virtual Keyboard' [type=user] 0 'Virtual Keyboard' [/snippet] And chuck --probe shows: [chuck]: found 1 device(s) ... [chuck]: ------( chuck -- dac1 )--------------- [chuck]: device name = "Jack Server" [chuck]: probe [success] ... [chuck]: # output channels = 2 [chuck]: # input channels = 2 [chuck]: # duplex Channels = 2 [chuck]: default device = YES [chuck]: natively supported data formats: [chuck]: 32-bit float [chuck]: supported sample rates: [chuck]: 48000 Hz [chuck]: [chuck]: ------( chuck -- 6 MIDI inputs )------ [chuck]: [0] : "EMU10K1 MPU-401 (UART)" [chuck]: [1] : "VirMIDI 1-0" [chuck]: [2] : "VirMIDI 1-1" [chuck]: [3] : "VirMIDI 1-2" [chuck]: [4] : "VirMIDI 1-3" [chuck]: [5] : "Virtual Keyboard" [chuck]: [chuck]: ------( chuck -- 9 MIDI outputs )----- [chuck]: [0] : "EMU10K1 MPU-401 (UART)" [chuck]: [1] : "Emu10k1 Port 0" [chuck]: [2] : "Emu10k1 Port 1" [chuck]: [3] : "Emu10k1 Port 2" [chuck]: [4] : "Emu10k1 Port 3" [chuck]: [5] : "VirMIDI 1-0" [chuck]: [6] : "VirMIDI 1-1" [chuck]: [7] : "VirMIDI 1-2" [chuck]: [8] : "VirMIDI 1-3" [chuck]: My code is simply: Rhodey s => PRCRev r1 => dac; MidiIn min; if( !min.open( 5 ) ) me.exit(); while(true){ min=>now; } I know it's not very interesting, but it should at least work - shouldn't it? Anyway, running chuck miditest.ck gives: [chuck]: MidiIn: couldn't open MIDI port 5... [chuck]: ...(RtMidiIn::openPort: error starting MIDI input thread!) So, what am I doing wrong? I'm assuming it's me, since I'm new to chuck. I haven't quite got past the urge to write my assignments backwards (for chuck) yet. Any help would be appreciated.
