MIDI promiscuous, in 2017?! (Now remedied!)

**EDIT** New version adds selectable MIDI channel, consider my complaining about MIDI channel no longer applicable!

Seriously, this thing responds on all connected MIDI devices to all MIDI channels on all layers.
A 4 layer synth app, without even the option to restrict MIDI to a single master channel is just baffling.

That being said, IK is on to something here, the result of the sample + subtractive synth controls is actually fabulous, the sounds are inspiring and rich, and almost as importantly, very tweakable.

It would be my main synth app if I could somehow control what it responds to.
Acceptable would be a single master channel and device selection option.
Optimal would be selectable MIDI channel per layer.

Another quibble is that while the MIDI CC mapping is well implemented, MIDI controlled mutes are abrupt and snap audibly.
Also, the sliders are impossible to adjust to a value accurately; you pretty much can't adjust a layer an octave down or up, getting any value to .00 is an exercise in frustration as it jumps all over the place.

If IK can remedy these issues, it's without a doubt a 5 star app; it tonally stands in the top group of iOS synths.

Developer Response ,

Thanks for your detailed review and feedback! Glad to hear you are enjoying the sounds. Stay tuned for future updates for improvements and new features, more to come! For returning a value to .00, try to double tap the parameter to reset it. Regarding any other concerns, please contact our Support team here for more details:

Ha potential, but some fatal flaws ruined it

Syntronik is a great app, that gives you many classic synths... but has two flaws that have pressured me to give this two stars instead of three. First off- you pay nine bucks for the app, and only get two to four sounds for each synth, then you must pay $70 for all the full synth sounds. This is just a cartoonishly stupid price for an in app purchase, i mean, that’s why this app isn’t getting nearly enough downloads and attention! Another reason is... I’ll put it bluntly; the keyboard is the most inconvenient ever! It spazzes out sometimes when you play at certain tempos, and with the new update, you have to press extremely hard on some of the keys; if at all! Maybe it’s because I’m using an iPhone instead of an Ipad, but this is still unacceptable keyboard quality! This app would be a beyond great resource if these flaws were fixed.

Not bad and a trip through music history.

Enjoyed purchasing instruments I spent thousands of dollars on during my 40 year Music career. No, not nearly as good as the real keyboard, but I like the ease to splitting, stacking, effect and mixer controls I was able to understand almost immediately. I had a lot of Jam points and I used everyone. Nice that Ikmultimedia offers them. Easy access to registration and even more rewards for doing so. They are a little bit over advertising on every product they offer, but since Syntronik works with SampleTank 3, useful to have that opportunity. This is a 100 percent romper preset playing software. I have been able to do a lot of custom work with the A B C and D Instruments to stack or layer together. I would just use two words, fun and reasonable!🎶🎶🎧
