StepBud vs Oscilloscope & Spectrogram

StepBud is a MIDI Sequencer with Audio Unit AUv3 plugin, Audiobus and Ableton Link. Add an unlimited number of steps to your sequencer. Your steps appear with a LED and a fader on top of your screen. You can change the active mode that your step faders displaying/controlling. - Set the current note or chord in range of the scale and key you selected with respect the range of the octave you want to focus, - Set the velocity, rate, gate time, modulation, pitch bend, portamento, probability and swing for each step, - Try increasing the rate and repeat count your steps if you want to add more flavor. - Send unlimited custom MIDI CC messages if you want to control your hardware or software synth parameters. - Lock steps if you don't want them to change their value. - Skip steps for creating interesting live performances. Below the step faders, you have a master fader where you can control your entire sequencer. It has two modes which you can change from the settings strip on the bottom of the app. - In copy mode, it assigns its value to each step. - In shift mode, it shifts up or down each step. If you want to go off-scale or try some crazy chords on some of your steps, or maybe on all of them, you can go to the Step Editor by double tapping the LED of the step you want to edit. In StepBud's powerful Step Editor, you can set your step's notes either from the virtual keyboard or your connected MIDI keyboard. Don't forget to enable MIDI in port of your MIDI keyboard or the you want to receive MIDI from the settings menu. You may also preview the selected notes by pressing the preview button in Step Editor for making sure you created the perfect sound for your particular step. You can also toggle the steps you want to disable by tapping its LED. If you long-press the LED, you can access a menu where you may copy/paste the steps around, remove them or edit them. If you enable the lock mode from the settings strip on the bottom of the app, you may adjust each visible step fader on the screen by a single swipe gesture without having to lift your finger up. Try to change your arppegio mode from the settings strip. You can sequence your steps up, down, up-down or random order. StepBud is a MIDI sequencer app and it does not generate sounds itself. You need to route its MIDI out port in the settings menu to the audio app you want to sequence. Please note that you need to have an iOS 11+ device and an Audio Unit host application such as AUM, apeMatrix, Cubasis, BeatMaker or Audiobus in order to use the StepBud as an Audio Unit plugin. And don't forget to route StepBud's MIDI out to the app or audio unit you want to sequence. StepBud's MIDI layer powered by free and open-source project AudioKit https://github.com/AudioKit/AudioKit Also, StepBud offers its core components for free on GitHub.

OSCILLOSCOPE & SPECTROGRAM is a powerful audio analyzer app and audio unit plugin KEY FEATURES - Run as both Audio Unit and standalone app - View up to three seconds of audio on the screen - Pause and scroll horizontally to browse back in time - Pinch to zoom in / zoom out - See both oscilloscope and spectrogram separately or overlayed together - Frequency trigger mode helps identify the precise frequency and MIDI note of sounds in the spectrogram - Stereo and mono views - Level based trigger mode has lookahead, pause, and zoom - XY mode shows stereo correlation - Automatically adjusts FFT size to fit zoom setting - Bark-frequency scale spectrogram shows nice detail at low and high frequencies - When zoomed in, the oscilloscope uses sinc upsampling to show you a close approximation of what actually outputs from your audio interface after digital to analog conversion, rather than just displaying raw audio samples. WHAT DOES THIS APP DO THAT OTHERS DO NOT? 1. Pause Button We can't emphasize enough how useful this is. You never have to worry about trying to catch short events that disappear quickly because you can watch the sounds go by slowly at a 3 second viewer scale, then just pause and scroll back if you missed something. When you get to the event you want to see you can pinch to zoom in right down to sub-sample level of detail, then zoom back out when you are done and zoom in on something else. This feature alone makes almost all other oscilloscope apps unnecessary because it means you can easily see ANYTHING that you need to see. 2. Frequency Identification Mode In frequency mode, when you touch the frequency scale on the right of the screen a blue line appears on the spectrogram. When you position the line above a specific frequency on the spectrogram, a panel on the left side of the screen displays the octave, note name, and MIDI number. You can then use the frequency timing oscilloscope to lock in on the exact pitch in cents so that you not only know which MIDI note that sound corresponds to but you know exactly how many cents sharp or flat. The ability to simultaneously see the frequency on the spectrogram and confirm it with precision on the oscilloscope allows you to quickly and easily identify musical pitches to a level of accuracy that have not seen anywhere else, not even in desktop software. 3. Trigger with Lookahead Almost every oscilloscope has a feature where it re-draws the screen each time the input signal level crosses a specified threshold. This is the main and most basic function of any oscilloscope. However, when setting the trigger at a high level to view the attack section of musical notes or drums, we miss the first part of the note. By using lookahead, this app allows you to see a few milliseconds BEFORE the trigger point so that you can see the whole sound you want to examine. 4. Carefully Designed Spectrogram In all spectrum analyzer displays, the upper end of the frequency scale is crowded, meaning that a single pixel corresponds to 10 or 20 frequencies in the frequency analysis. In many other analyzer apps one of two things occur: either 9 out of 10 frequencies in that upper range simply get ignored and disappear from the spectrogram display, or all 10 frequencies combine together to make the pixels in the upper range appear brighter than low frequency sounds of similar volume. This may seem like a technicality until you run a sine sweep or a 20 KHz tone through the analyzer and find that large sections of the input simply aren't displayed on the analyzer screen. Looking at these kinds of test signals on a spectrogram is the primary way that we test and evaluate the quality of audio effect plugins. If a spectrogram is to be of any real use as an analysis tool, it should do this right. Other spectrograms often mess up the lower frequencies too, either by making them take up too much space or by making them very pixelated. This spectrogram carefully avoids these problems.
