NOTE: Since version 1.2, the preview-sound function changed from single tap to long-press! So the functionality is not gone, but we changed to long-press to not interfere with the music.

If you are running iOS7, the app can sometimes go silent and not produce any sound. If this happens, double-tap the home button to enter the multi-task view, scroll to Yellofier and swipe it upwards out of the screen. Then start Yellofier again, and it should make sound again. Sorry for the inconvenience, we hope that Apple will fix this issue as soon as possible.

Customer Reviews


I love this app, its awesome ive been using it for years. please add midi sync, ableton link would be great, all the other apps i use are taking over.


Brilliant fun for making tunes. It allows u to create many happy accidents and is powerful enough to make complete songs. The ability to pitch every step is awesome and makes it easy to come up with melodies and bass lines. The time line sequencer is great. I have already made a fun techno album.

A few requests in order of importance:

1. Currently, each steps sample is cut off by the next step (if there is a sample in the next step). This makes each track monophonic. I would like to see the option to select 2 different modes to determine how each sample is played.

Mode 1 could be how the app currently behaves.

Mode 2 could allow the sample to play to the end. Currently I have issues with some kick drums (such as the 808 kick) or long synth notes being cut off as they play for longer than a step or have a long release time.

2. More tracks please! I know fits nicely on the screen so u can see everything but maybe u could squeeze on a fifth track or just increase to 8 tracks which would mean u would have to scroll down to see the other tracks.

3. It can be tricky avoiding clicks I would like to see an auto fade in / fade out implemented for each sample. An ADSR would be nice too but perhaps too much to ask!

4. I would like to see a more regular sounding delay with different tempo synced speeds. Again, option not to be cut off by the next step. Some additional effects too - perhaps LP/HP filters, stutters, pitch shift effects, etc. Similar effects to Sugar Bytes Effectrix.

5. I would like to be able to loop more than 1 bar. An option to simply type in which bars you would like to loop would be great.

6. Currently limited to 100 bars. Increase to 200 bars.

7. Panning per sample please.

8. The ability to save sampled user banks, so you could use them in different projects.

9. At least 2 more user banks for each project.

Please continue to develop this app! Thank You!!
