6.99$ -> FREE FOR EVER. Get it and spread the word. From: Marcin (the developer) >>> Hi everyone. The new iOS 11 is coming soon but sadly Right Note is beyond updating to run on it :( The good news is that for the last months of its life I decided to give it out free :) It's an educational app and a lot of musicians found it very helpful so it's best for as much people to have a go with it instead of just "killing" it. If you will want to use it after the release of iOS 11 you have to save some device with an older iOS. And if you like the app and would have gladly bought it for the full price but cant (as it's free) you can check out my other apps: "Tangled FX" photo effect and "BaM Video Delay" sports app. Thanks to all of you and have fun with Right Note. >>> ON-OFF switch not working ? There is a small compatibility glitch with iOS 10 but there is a workaround: - first TAP the switch to the state you want - then DRAG the switch by the knob to the opposite state Although the second step is counterintuitive this makes the TAP to get through the iOS to the app. [Old description] @ Try out new "Intervals in Context" @ Now with microphone recognition - play with your instrument @ Right Note - An ear training app for learning Interval, Pitch and Melody recognition REVIEW BY Lhp1: @@@@@ The best ear training app so far I used to say that I would never spend more than 10 bucks with an app, but after trying the lite version I had to get this one. I love it, good job. Featured in US "What's Hot" WHAT CRITICS SAY: [www.notreble.com] I found Right Note to be worth a special mention, primarily due to the inclusion of the microphone This is what really counts here: the ability to develop your relative pitch and use it in context on your instrument [iosmusician.blogspot.com] This feature {microphone recognition} is what sets the app apart from all the rest, especially in Melody mode Right Note helps you develop that 'sixth sense,' or 'instinct,' needed to figure out what note is where, with out even thinking about it Brilliant 5/5 WHAT'S UNIQUE ABOUT RIGHT NOTE ? @ Microphone recognition now you can play using your own instrument @ Your not just answering questions before each lesson you can train hearing given intervals with random root and notes in different octaves to get the feel @ You learn from your mistakes after a mistake you can analyze the right and wrong answer instead of just moving to the next question @ Melody dictation intervals and pitch is a good practice but your main goal is melody recognition @ Intervals in context so you know your intervals but can't hear them in a melody? Try out this exercise to bridge the gap @ Highly customizable a wide range of settings and options giving you the much needed freedom outside the given lessons KEY FEATURES: - Four exercise modes: Interval, Interval in context, Pitch and Melody - Highly customizable settings - Note range from C1 to C8 - Lessons for all modes, from beginner to expert - Learn from your mistakes: retry all you want or use the show answer option - Train listening to random intervals and pitch to get the feel - Choose between controllers for a different approach: pads, full keyboard, "octave" keyboard - Easily scrollable keyboard with a visual scrollbar showing the full keyboard - Music notation - choose between American or European notation and shift octave numbers - Bonus virtual piano MICROPHONE: - New way to answer instead of using GUI controls - Great to get the feel of a live instrument - Detects wide range of notes - from C1 to even C8 - Octave equivalence option - Tested on pianos, guitars, flute, harmonica and other - If you plug in a mic you can still use the built-in speaker

RRS CL1 AUv3 plug-in — comes as time-limited Demo-version for you to try. It gives you 5 minutes of Free play time. (You can reload the CL1 AUv3 plug-in as many times as you want, thereby you get the Demo period again and again.) Unlimited version of CL1 AUv3 plug-in comes as In-App Purchase. CL1 is stereo and mono audio signal dynamic range compressor. CL1 compressor has distinctive sound allowing its usage not only for technical purpose of dynamic range compression but also for artistic sound coloration, which happens due to usage of saturation with even harmonics, dithering that gives effect of «air» and oversampling with non-linear phase response that gives effect of «depth». CL1 compressor besides main dynamic range compression module also contains limiting module («limiter»), which allows controlling peaks passing through the compressor, mid-range equalizer module doing ISO-226 curves equalization and input signal or gain reduction VU-meter with lamp indicator for limiter operation control. CL1 compressor has adjustable high-pass filter for side-chain signal, also supports «parallel» compression and M/S operational mode. FEATURES: • Two different attack modes: «fast» and «slow»; • Softness of compressor characteristics control; • 6 operation modes: double mono, mono with external side-chain signal, mid channel, side channel, M/S, linked stereo; • Mid-range equalizer and Side-chain signal high-pass filter; • Pre- or Post-Limiter; • Attack and Release times multiplier; • Internal Dithering; • Parallel compression; • 8x oversampling and 64-bit floating point processing; • External Side-chain. • A/B comparison; • 2x/4x/8x Upsampling; • Macro controllers; • Built-in Gain Match; • Scalable GUI. ATTACK MODE: • In «Fast» mode when control signal reaches Threshold the compressor immediately and very fast starts to lower the signal level slowing down by exponential law; • In «Slow» mode the compressor in the same situation starts gain reduction very slowly thus most attack of the signal passes through. MID SCOOP: • The built-in mid-frequencies equalizer is based on mid-frequency range equal loudness curves design and can be used as another tool to position instruments, with ability to highlight backside elements or to add a bit density to frontal elements and move them back at the same time. CL1 developed on the basis of «МОЛОТ» compressor by Vladislav Goncharov. To use CL1 as a plug-in, you need an AUv3-compatible host app like GarageBand, Auria, AUM, Cubasis and more — CL1 will appear in the list of Audio Unit extensions for effect plug-ins in the host app.
