Re: [LAU] pianos with built in recorders?

The big disadvantage with USB MIDI, is that you can't connect two devices, which only have a USB slave port. One of them needs to be a USB host (with USB MIDI support). This role is normally played by the computer. But you can't, for example, connect your digital piano with an USB MIDI output directly to a hardware synthesizer, which only has the same USB MIDI output slave connector (or only DIN MIDI). There are a few keyboards, which have USB host functionality (e.g. Yamaha Motif, Korg Kronos), e.g. you can directly connect another USB keyboard to them, but the vast majority of USB MIDI devices doesn't. DIN MIDI also has the advantage, if you accidentallly pull out the cable, the MIDI port in your application (ALSA, JACK, whatever) doesn't go away and doesn't needed to be reconnected. On Windows you often even need to restart an application to recognize newly/re-connected USB MIDI ports. (Of course, if you have an USB-MIDI-adapter built into a cable, it's basically like a direct USB connection.) Chris
