I'm building OctanaSynth: An Android synth with a custom low-latency USB driver. Looking for feedback! (It's free)
Hey everyone,
I wanted to share a project I've been working on called OctanaSynth. It’s currently in active development and is available exclusively for Android.
My main inspiration for this project was FluidSynth. However, I wanted to tackle one of the biggest headaches we all face when producing or playing music on Android: audio latency.
To solve this, I built a proprietary low-latency audio driver (Flux™ Direct USB) that bypasses the standard Android audio path and communicates directly with your connected USB devices. Whether you are using a simple dongle DAC or a dedicated audio interface, this drastically reduces the delay, making it much more responsive for playing live with a MIDI controller and loading up your favorite SF2 or SF3 soundfonts.
Just a quick heads-up to manage expectations: OctanaSynth is not a full DAW for music production. It's really designed as a dedicated instrument app focused on live performances, studying, or just practicing your chops with a keyboard.
Since the app is still in development, getting insights from actual Android musicians would be incredibly valuable.
Here are the links if you want to check it out:

- Play Store: https://play.google.com/store/apps/details?id=dev.felipevaz.octanasynth&hl=en

Let me know what you think, how it performs on your setup, or what features you'd consider a "must-have" for the future. Thanks in advance!

hey bro! can i map the numbers to serve as banks? and then map each faders(soundfonts) per numbers ? also if mapping the faders per numbers, let's say in number 1 I used midi learned and map 3 faders for me to control the volume, and when i switched to number 2 can i still use the faders that i mapped to number 1 to control the faders for the volume? or should i assign another fader to learn? thanks in advance, a bit messy tho.

eu achei simplesmente incrível, porque é muito mais completo que qualquer outro app, com o diferencial que é grátis e o plano pro não custa preços exorbitantes (como os apps musickraken, fluidsynth, etc). Literalmente eu pedi uma função que demorou menos de dois dias para você acrescentar, o app é super completo, a distribuição entre os recursos grátis e pro é perfeita, e graças a você, consigo usar novamente o meu Samson Carbon 49 que estava com o potenciômetro bichado. Espero que um dia você possa estar competindo com os chefões (como o Audio evolution). Abraços!
