JamKoo is designed for live performance worship band and practice.
JamKoo can turn your old keyboard to a realistic grand piano.
JamKoo allows you to mix and record backing track with realistic virtual instruments.

Application Scenario

- Piano: Connect your keyboard to iPad, iPhone via USB-MIDI or Bluetooth MIDI. Play and record your performance with this app, share the recording with your teacher. The piano sound and tuning is more realistic than an ordinary electric piano.

Jamkoo review

There is a problem with Sting assembly 2. Not only are the keys sticking, but when you hit a chord it hits some weird notes. Some of the Chinese instruments are spot on. I will give this 4 out of 5, probably a 2 if the recordings I need required using string assembly 2.

Please investigate and fix so I can come back and rate it a 5. I uninstalled and reinstalled and still have the problem.

Thank you for the feedback, we will trace it.

Great start

Allow for octave change and dual keyboard option on play screen. Leave list of samples where they are when choice is made instead of having to start from the top of the list. Some of the samples are familiar and have the loop popping especially in the string ensembles. Aux3 or at least an effects array. When you build a monster you have to feed it. Lol

Yes, these are on the TODO list. Enjoy!

Must give 5 stars for an app that is loaded with features

Updated: app just keeps getting better! I hope that musicians get a chance to use this app and supports the developer. I downloaded this app when it first came out (I wasn’t a tester, but would have loved to have been a part of such a quality app) the crisp distorted guitar leads, the pop that the slap bass brings, the lows that don’t break up and clip. The sexy smooth sound of the sax, the lush sounds that the string ensemble offers, I’m impressed. I use GM’s “pure synth” as well as and Jamkoo offers amazing quality that in most cases outshines it’s competition!
*** Side Note*** However the JAZZ GUITAR has a looping issue that renders it unusable... after the note is struck “after the initial Attack, and Decay ...the sustain loop just wacks out and loops from the initial attack, so instead of a smooth sound, it become choppy.”

I love this app, and I see it becoming a must in any ISO users toolbox. It’s a GREAT romper, and again my hopes are that the developer get tons of great feedback, support and word of mouth users. I for one will tell everyone I know to give this a look!

Thank you, this is a start point. Don’t hesitate to request for new features.
