Connecting Roland Keyboard & Imac Intel Options

[BlackNote]

Hello,

I recently discovered GarageBand on my iMac and would like to connect my Roland HP 530e keyboard in order to record partitions & play sounds from GB on my keyboard. I got my hands on a ESI MIDI Mate cable and connected it. GB indicates that a MIDI device is connected, the Audio MIDI setup correctly shows the ESI MIDI Mate but nothing works. I can't get any information from the keyboard in GB and sounds won't play.

I'm sure I got something totally wrong, thats why I'm asking for your help. Thank you in advance for any useful tips.

Regards,

Hello,

Thank you all for answering so fast. I've tried pretty much everything listed above, but I'm not getting much further. For some reason, GB only detects a MIDI device but is unable to connect to it when I choose inout/output audio in the preferences. System preferences aren't much help either since there is no indication of connected devices such as a keyboard. The only positive signal I'm getting is via the MIDI setup utility, indicating indeed a connected ESI MIDI Mate cable, and GB detecting the presence of a connected keyboard. Other than that, I can't find any way of getting this to work. I'm pretty sure I'm making a fundamental mistake, too evident to be seen here I guess.
(I did press "record" each time, but this didn't matter...)

Shouldn't I have to select my keyboard in GB under Audio menu in the preference pane? My MIDI Setup tuility only shows the ESI MIDI Mate. Shouldn't there be a keyboard as well?
I'm sorry, but I know myself pretty well around GB and playing the piano/composing, but when it comes to computers and connecting different components, I sometimes get lost.

Thank you so much for your help.
