Ive had this problem on windows and mobile. After posting on youtube, the volume using midi isnt as loud as synthesia's midi.
If you compare the first video with the second, see music needs to increase midi volume. Ive had this problem for months and the sound in see music i put on max but it is still not enough.
I also have a problem with recording AUDIO with a phone in see music. The normal camera app can record audio directly from keyboard, but see music cant record audio connected to keyboard. It seems that see music can't take audio inputs from audio cables, but the i phone camera app can. PLEASE HELP thanks
