24 alternatives to Let’s Bend – Open-Source Harmonica Bending Trainer

Hi HN, I built a simple harmonica practice app that shows real-time pitch and bending targets for each hole. It helps blues harp players visualize their technique and improve intonation. No tracking, no ads, open source (MIT). The app is available on F-Droid and GitHub. You can find more details here: https://letsbend.de Feedback welcome!

    Hello HN, this has been my personal project for quite some time now. It has been a slowly evolving project over the years and its core function is for users to expose themselves to progressively more difficult lessons of music notes. NOTE: It is free and there are no ads. There is an in app purchase but most of the app doesn't require it.

    I'm building a video conferencing app designed to facilitate better remote piano lessons. My hope is to solve a lot of the challenges piano tutors and new students deal with when taking lessons through Skype/Zoom. It leverages WebRTC's data transmission to send media, MIDI state, and (eventually) send sheet music files and other musical data. I'm surprised with how well the MVP has worked and would love to hear any feedback or suggestions!

    A few years ago, right after high school, I decided to try to make a simultaneous translation app for Android as a side project, it took longer than expected (about 2 years) and I had to make a lot of compromises (I had to use Google's API and therefore make users use a developer key because at the time there were no free solutions for speech recognition and translation that had good quality). At the end of university, I decided to pick it up again and finally, using OpenAi's Whisper for speech recognition and Meta's NLLB for translation (with both running locally on the phone), I managed to…

    I always found sheet music way too hard to read - and I literally spent a year at a company building a sheet music rendering engine. I wanted an app that would display music like the tutorials on YouTube, but not be focused on upselling lessons etc. like most current apps, and also would let me import my own files This works on MIDI files. If it’s a valid midi it probably plays. Since releasing, I did add a subscription for classical music - on a theory that most normal users don’t know what a midi file is. It changed about a month ago from an up front price to in app purchases and/or a…

    Author here - one of the most notable facts about the app is that it's made entirely in Godot Game Engine! I think it's great for apps like this because it makes it especialy easy to iterate on GUI designs such as this one. Feel free to ask me anything about Chord Chart Memo, or my experience with Godot.

    A few months ago I had a silly idea of making a mobile app that used the accelerometer to track the slide motion for playing a virtual trombone. Just wanted to share the story of bringing it to fruition here on hn. I started out spending a couple days trying to get something cross-platform going in Flutter, but it soon became clear that wasn't the best fit, seeing as I'd need native hooks for most of what the app needed to do, and it wasn't yet clear it'd be possible at all. So I switched to making it an iOS app in Swift. The accelerometer data turned out to be not nearly accurate enough to…

    We're happy to present Veena Chromatic Tuner, an app we've developed for musicians, instrument makers, and ethnomusicologists who need more than just a standard chromatic tuner. Our goal was to create a tool that not only supports pitch detection but also provides deep support for diverse musical intonation systems and offers intuitive visual feedback. The Problem We're Solving: Many tuners are good for Equal Temperament, but has limited support when it comes to the Just Intonation, microtonal music, or the specific requirements of instruments like the Veena where fret positions are…
