Can you play piano on a floppy disk normally?
Yes. I was able to play prerecorded floppies. I presume that they were original from the initial purchase.
Can you measure the keyboard(maintenance mode→Keyboard measurement)
but can not record your performance?
Yes. I did the Keyboard measurement routine. Loud and clear.
Can you enter the test mode and check the key and hammer sensor?
Yes, I was able to enter Test Mode and navigate to the Key and Hammer Sensor pages. However, nothing happened. I am not sure on how to activate that test or if it is an automated procedure. For example, I get to the Sensor sheet test:
(1) KEY SENSOR DEPTH TEST
However, I cannot get to the screen:
(1) KEY TEST KEY NUMBER= xx
With recording, I hooked up the MIDI cables to my Mac and was able to record to Garage Band. Only a few of the notes were recorded, but with extremely low velocity.
I think that this is where I might need to do more checking. Weak velocity on MIDI output to the computer and just a few notes when played back from the console.
