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 Ivoks AUv3 instrument — comes as time-limited Demo-version for you to try. It gives you 5 minutes of Free play time. (You can reload the RRS Ivoks AUv3 instrument as many times as you want, thereby you get the Demo period again and again.) Unlimited version of RRS Ivoks AUv3 instrument comes as In-App Purchase. Features: • Analog Emulation; • Undo/Redo; • A/B comparison; • 2x/4x/8x Upsampling; • Macro controllers; • Scalable GUI. On the centre panel are located two audio-frequency oscillators: • OSC1 offers frequency Band regulator, five Waveforms and controls for LFO Modulation level plus OSC2 Cross-modulation; • OSC2 offers the same frequency Band and Waveforms, an independent control for Modulation depth, plus Detuning. Underneath these located the mixer, which offers level controls for the two Oscillators, the Noise generator, and Saturation Drive. To the right of these, located the filter block. The top half is a standard ADSR envelope — until you flip the switch «Envelope mode», when it becomes a repeating AD-envelope instead. The four controls at the bottom adjust Cut-off, Resonance, LPF to BPF switch, Modulation level and Envelope level. Next after the filter is the amplifier block, it also has ADSR envelope along with another Modulation level and Velocity sensitivity control. Again, the envelope can be switched to a Repeating Mode that generates a triangular waveform determined by the Attack and Decay settings, providing some of the instrument’s most distinctive effects. The leftmost panels house the Modulation (LFO) controls (top), Mode which offers four waveforms, including noise, and a stepped Function for sample & hold (S&H) effects, well as Speed control. And global settings such as the master Tune, master Volume, Legato mode, Monophonic and Duophonic operation and Unison switches, and the Glide control. To use Ivoks as an instrument, you need an AUv3-compatible host app like GarageBand, Auria, AUM, Cubasis and more — RRS Ivoks will appear in the list of Audio Unit instruments in the host app. MIDI CC Implementation Chart: • CC#003 => HQ • CC#009 => Saturation Drive • CC#014 => Modulator Speed • CC#015 => Modulator Mode • CC#020 => Filter Attack • CC#021 => AMP Attack • CC#022 => Filter Decay • CC#023 => AMP Decay • CC#024 => Filter Sustain • CC#025 => AMP Sustain • CC#026 => Filter Release • CC#027 => AMP Release • CC#028 => Filter Envelope Mode • CC#029 => AMP Envelope Mode • CC#030 => OSC1 Band • CC#031 => OSC2 Band • CC#085 => OSC1 Waveform • CC#086 => OSC2 Waveform • CC#087 => OSC1 XMod • CC#089 => OSC2 Detune • CC#090 => MOD to OSC1 • CC#102 => MOD to OSC2 • CC#103 => OSC1 Level • CC#104 => OSC2 Level • CC#105 => Noise Generator • CC#106 => Global Tune • CC#107 => Global Glide • CC#108 => Global Volume • CC#109 => Global Voice • CC#110 => Global Unison • CC#111 => Global Retrig • CC#112 => Filter Cut-off • CC#113 => Filter Resonance • CC#114 => Filter Mode • CC#115 => MOD to Filter • CC#116 => Filter Envelope • CC#117 => MOD to AMP • CC#118 => Velocity Sensitvity
