Frickable

This was a BIT better than a different AU soundfont player called “Fontstack”, however, the downside is that I CANNOT USE DRUMS ON ANY CHANNEL BUT 10, I NEED IT TO WORK ON ALL CHANNELS, WHY MAKE IT SO COMPLEX? FL STUDIO MOBILE DOES BETTER THAN THIS! I JUST WANT WHAT SOUNDFONT I CHOSE TO BE PLAYING! NOT COMPLETELY JAILBREAK THIS APP! PLEASE SIMPLY! I ALSO DO NOT WANT REVERB!

Wavetables not working

Everything works but the only thing that doesn’t is the wavetables every time I try to press library on the app freezes. This only happens on my iPad when I do it on my phone it works perfectly

Amazing app, super fun to use and work with!

My only issue is that MIDI will cut out for a split second sometimes, it’s usually just one audio track but sometimes it’s all of them. (Audio tracks that are bs-16i of course)
Is there any way you could possibly fix this? It can be incredibly noticeable and a bit frustrating at times.

Response from developer

Version 5.0.6 resolved the issue. I apologize for any inconvenience this may have caused.

It’s goated but

It still crashes. I have no idea what keeps causing this and It’s pissing me off. It feels like the system wants me to blame this. Either that or it’s just my storage. It’s still really good but note to self: don’t use too much of it.

外部音源として使用する際の不具合

このアプリで自分の中で革命が起きました。

しかしながら、不具合(?)が見つかったので報告させていただきます。
(環境:iOS17.4のGarageBand)

外部音源として使用する際にbs-16i(Legacy)を選択すれば設定中のInstrumentの音が鳴ります。
しかしbs-16iを選択した時、他のKeyboard領域からコピー&ペーストしたデータの場合に設定中のInstrumentの音が鳴らずピアノの音になるという現象が起きております。

改善方法があればご教示いただけますと幸いです。

Response from developer

GarageBandでご利用になる場合には、Settings > Overwrite Input MIDI Channelを任意の値にご設定ください。bs-16i側は指定されたChannelのみ発音する格好となります。
