Brought to you from the unique world of MrFranz K - who's inimitable presentational style enlivens any subject, the Synth! iPad app from retronyms, offers a 5-voice synthesizer and sampler with over 40 preset synth voices.
PROS:
Polyphonic touch screen synth keyboard large enough to be used as a real piano
Excellent Value for $0.99!
A decent selection of various synth sounds, and fun "sampler" mode included
You can hear the sounds as you are selecting them from the list
Mod Wheel effects each sound in a relevant way
Includes adjustable Delay and Distortion effects to augment sounds
with atmosphere and edge
Portable musical fun for kids or pros!
CONS:
Drum sounds included, but no metronome or backing drum beats
Could use a wider choice of sounds ( but they could easily increase it
via update )
Delay effect does not show BPM, and no "tap tempo"
Distortion effect is very "digital" sounding ( harsh and crisp )
Basses could be more "bassy" in the low end
Mod wheel, but no "pitch bend"
Pros may wish for more detailed control over sounds
OVERALL RATING: Hard to go wrong with this sort of price tag.
Worth checking out their other apps such as: Doppler Pad, - a more fully functioning sound tool and StudioTrack - for multi-trackrecording.
