OscDrax vs BeatMapper

Your Fingertips Create New Sounds OscDrax is an innovative iOS waveform synthesizer that enables professional sound design through intuitive touch controls. Simply draw waveforms with your finger to instantly create original tones. Combine four independent tracks to build complex, rich soundscapes. Unleash Creativity with the Waveform Editor Our waveform drawing system maximizes the potential of touchscreen technology. With 512-point high resolution, accurately reproduce any waveform you imagine. Classic waveforms like sine, triangle, square, and sawtooth are also available at a single tap. Designed for everyone from beginners to professionals. 4-Track Multi-Timbral Synthesis Each track operates completely independently with its own waveform, frequency, and volume settings. Layer multiple tracks simultaneously to create thick, complex tones impossible with a single oscillator. Professional Controls Frequency Adjustment (20Hz-20kHz) Full coverage of human hearing range. Logarithmic scale slider provides musically natural control from bass to treble. Portamento Function (0-1000ms) Smooth glide effect between pitches. Faithfully reproduces the warm expression of analog synthesizers. Individual Volume Control Fine-tune each track's volume from 0-100%. Achieve ideal balance with precision mixing.

BeatMapper turns your iPhone into a grid of coloured pads. Tap a pad to play its sound. Turn on Loop and the sound keeps repeating, so you can stack pad on pad and build a pattern while it runs. Tap a looping pad again to stop it. Seventeen sound sets are built in: drum kit, percussion, music box, bass, sine tones, chiptune, everyday sounds, cartoon effects, sci-fi effects, interface sounds, phonemes, greetings from around the world, the English alphabet, English numbers, Japanese words, French words, and the system sounds. Nearly four hundred sounds in all. Every pad shows what it is doing. A white square shrinks inside the pad as the sound plays, so you can see at a glance where each loop is in its cycle and how the parts line up against each other. Five buttons run along the bottom. Playing Length decides how long a sound plays. Loop makes it repeat until you stop it. Drag Action sets what happens to the pads your finger sweeps over. Randomize plays a handful of pads at once, and All Stop clears everything. The caption above each button names the item currently chosen, so nothing hides behind a symbol. The pads fill the screen. The grid is worked out from how many sounds the set has, always at least four across, so the pads stay large enough to hit with a finger. Randomize shuffles the layout, keeping each sound with its own colour, and Reset puts them back in order. Playing Length decides how long each sound runs: how long you press, the sound itself, the longest sound in the set, or that length with a little drift. Press Length turns the pad into a key you hold. Aligning to the longest sound makes every pad repeat on the same beat, and the drift spreads them so the phases pull apart and the pattern keeps changing. Auto Play taps the pads and buttons on its own, at a pace you set, and the gaps are random rather than even. Leave it running and the app plays by itself. Pro unlocks two more things: importing your own sounds from any folder on the device or in iCloud Drive, and recording what you hear as a 48 kHz / 24-bit WAV file in the Files app. Other things you can set: what appears on the pads, polyphonic playback on or off, background playback so the sounds keep going when you leave the app, and whether the status bar and home bar are shown. A Quick Guide inside Settings explains every control. No account, no setup, no menus to learn. Open it and play.
