Could there be anything more sweet than four-track?
Tascam is bringing it all the way back with this iPad app:
Record one track at a time using the built-in mic or a headset microphone connection, monitoring on authentic VU meters.
A cassette transport with position counter tracks your position while you mix with level, pan and EQ controls. When you’re ready to mix, the built-in mixdown function saves your song as a CD-quality WAV file.
Your mix appears in iTunes when you’re finished, ready to share with friends and bandmates.
