MIDI Controller App is a Midi Keyboard designed to easily fit in the musician's pocket and still can be used in big music studio. Use the piano keys to play midi notes, trigger drum samples using drum pads, apply pitch bend and modulation with sliders and control midi cc (control change) with rotary controller knobs. MIDI controller does not required any additional software or drivers and can connect to any DAW including Logic Pro, Cubase, Ableton Live, Pro Tools, Studio One, FL Studio, Bitwig Studio, Reaper, Garageband etc. Just connect it either via Bluetooth or with just a USB cable in IDAM mode. Overview: - Trigger MIDI notes using piano keys - Trigger Drum Samples using MIDI Drum Pads - Pitchbend control using pitchbend slider - Mod and Vibrato control suing modulation slider (CC1) - Control parameters using 8 control knobs (CC1 to CC8) - Change octave and keyboard size Midi Connectivity: - Inter App MIDI - Inter App connectivity with iOS apps - USB MIDI - IDAM (Inter Device Audio MIDI) connectivity with USB cable - BLE MIDI - Bluetooth connectivity (wireless) - Network MIDI You can use MIDI Learn feature available in most of Digital Audio Workstations and Synthesizers to link the control knobs easily. Also you can adjust pitch bend sensitivity in your instrument to use the pitch bend slider according to the requirement. Midi Controller app works best with iOS and macOS.

About

TB Lowtone

This app is an innovative bass synthesizer and AUv3 plugin that uses loudness-domain harmonic synthesis for deeper, more consistent bass sounds. It features multiple oscillators, modulation options, and built-in effects, plus an AI randomizer for creating new patches.

Highlights
  • Loudness-domain harmonic synthesis
  • 3 analog-simulated oscillators
  • Voltage-controlled noise synthesizer
  • AI randomizer for patch generation
  • Extended LFOs and ADSR envelope
  • Pro quality effects (reverb, chorus, delay)
  • AUv3 plugin support

TB Lowtone is an innovative bass synthesizer app and AUv3 plug-in featuring three analog-simulated, voltage-controlled oscillators with a large variety of waveform algorithms, continuous pulse-width modulation (PWM), Frequency Modulation (FM) and oscillator hard sync, complemented by a voltage-controlled noise synthesizer, parameter modulation a re-designed non-linear voltage controlled filter. TB Lowtone is the world's first bass synthesizer featuring loudness-domain harmonic synthesis, creating deeper, more consistent and production-ready bass sounds compared to conventional synthesizers operating in the (linear) amplitude domain. TB Lowtone also features an AI randomizer that generates new patches with a single click, and which learns from the patches you have already created to generate new, personalized patches! Loudness-domain synthesis Loudness perception of tones and harmonics is known to be highly non-linear and intricately frequency and level dependent. Equal loudness contours, or Fletcher-Munson curves demonstrate this drastic effect for sine tones, which is especially relevant for low frequencies. The loudness of a synthesizer bass note, and all its individual harmonics, will therefore depend strongly on what note you play on your synth's keyboard. To overcome the resulting inconsistencies in loudness and timbre, TB Lowtone features innovative, loudness-domain synthesis algorithms that adjust each harmonic individually to compensate for loudness deviations across frequency. Modulation and FX TB Lowtone provides two extended low-frequency oscillators (X-LFOs) featuring a wide range of waveforms. The LFOs can be beat and key synced, with a configurable onset delay and a specific number of cycles to run. In addition, a conventional ADSR envelope with configurable onset delay is provided. To top if all off, a gate editor designed to quickly put together modern production modulation patterns is available as well to modulate a range of VCO, VCN and VCF parameters. Reverb, chorus, and delay effects and a high-quality peak limiter are provided to produce production-ready sounds. Features: - 3 VCOs plus a VCN featuring a wide range of waveform algorithms - All VCOs support hard sync, pulse-width modulation (PWM) and frequency modulation (FM) - Lots of filter types for spectral shaping - 2 LFOs, one extra envelope and a gate editor for parameter modulation - Pro quality effects (reverb, chorus, delay, peak limiter) - Unique loudness domain synthesis algorithms - A smart randomiser that learns from your patches - AUv3 with resizable UI and dozens of color themes to choose from - Preset management including import and export options - Undo, redo, A/B switching What you should know: - Licenses acquired for this platform are not compatible with other platforms. - Audio Unit (AUv3) extensions require an iPad mini 2, iPad 4 or later models.

Verdict

The call

The clearest difference is review sentiment: TB Lowtone at 85% against MIDI's 29%. TB Lowtone also leads on rating (4.4 vs 4.1) and update cadence (every 3 months vs every 12 months). MIDI's advantage is price ($3.99 vs $9.99) and iOS requirement (11.0 vs 13.0). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
