bismark bs-16i is a 16 multi-timbral playback sampler. It loads SoundFont and DLS (Downloadable Sounds) as WaveTable and can be used for keyboard instruments, MIDI sound modules, and MIDI file players.

bs-16i has the synthesizer engine that has been adopted for many professional/commercial types of equipment. Using SoundFont / DLS libraries, you can play with your great number of instruments. With Hi-Res Engine option prepared as an In-App purchase option enables high-quality and low-noise audio outputs by 100% floating-point calculations.

All standard MIDI messages are supported, and your iPhone and iPad can be used as a GM (General MIDI) sound module by using pre-installed GeneralUser GS SoftSynth v1.44.sf2 (S. Christian Collins).

As a keyboard instrument, you can play with the scalable screen keyboard, pitch bend wheel, and many control change controllers.

Love this app

I’ve used this app for a number of years but just came across this bug. After adding portamento to a patch I tried (multiple times) to save it as a scene. After it “saves” the portamento setting is at 0. I’ve tried saving it as a new scene, overwriting an old scene, changing the sound font, and everything else I could think of but nothing saves the portamento setting. This is not the on/off setting (that gets saved) but the amount of portamento. Why is this?

Especially with the latest update!

I have been using bs-16i for a long time, and it works beautifully. It is very easy to import any sf2 file, either purchased ones such as Sound Factory files, or those you can make yourself with something like Polyphone.
The biggest negative I had was that bs-16i would not save the sound font setting with patch info in a host app, such as AUM; this required you to manually load the correct sound font, or make up a custom sound font that contains all the sounds you’d like to have on hand. With the latest update, this limitation is gone, and bs-16i is working like I have wanted it to all along.
BIG THANKS to the developer for getting this feature working!

Must have app!

As you probably know the purpose of this app, I’ll just say that it does it very well. Extremely efficient app, was running several instances in AU mode without any issues. And I was using huge samples (1gb+) in all of them. Excellent developer!

One small request, if you could make the defaults, when starting a new instance, with all fx - Off, and volume at middle position, this app would simply be perfect! I always use various external fx, and the volume is a bit too loud by default. Thanks!
