thank you very much for Your detailed answer,
unfortunately the track you ear is not an external audio signal: all the track in this mp3 file is played with the standard instruments of the keyboard
the recording is made on the UK beat style (style A06) from which I turned off the A12-A13-A14 traces
tempo :124 bpm
tracks:
B025 phaser piano
D055 ovd.gt.m4
D035 dist.gt.3
E022 synth string 1
i simply saved the song on 1 of the 5 "user song slot"
and then i recorded the wav file in the following mode:
- select, in the song sequencer, the user song i wanted to record in a wav file
- push the "audio recording" button
- select the "casiowv*.wav file to write (between 1-20 slots on the SD card)
- push again the "audio recording" button to start the recording
- wait 3-4 seconds to see if the recording timer starts counting
- press "start" button to play the song i want to record
- push the "audio recording" button to end the recording
but still, every time i try to do this operation, through the headphones I hear in some part of the song the beats go faster or slower or "syncopated" / "crossed"
the wrong part is never the same part: if i try to record again the song, the wrong beat It occurs at another point, or does not occur,
but the cases in which all is well are few
thank You again
Stefano
