This app is capable and complex FM synthesiser that can create rich and very strange sounds combining up to 10 sound generators. Every generator can be adjusted up or down from the main frequency almost without restrictions in range. There are 4 possible wave forms for the generator output and you can tweet the volume, modulation and add some tremolo effect. You can listen to the result sound while you are adjusting the new generator and just add it to the result when it sounds good. With the Sound Maker Synth you can also add reverb and then play it as a one voice synth using the one octave keyboard at the top. The app is very capable to create some strange and alien like pad sounds as some dubstep bass.

Audio Object is a pocket-sized music instrument for iPhone. It looks and works like a small piece of hardware — a wooden body with an instrument panel on each face. Pull the wood edge and the body rotates to the next face. WHAT IT DOES - Four-track looper with bar-quantized recording and per-loop trim - Three-voice drum machine as the click track — kick, snare, hi-hat with a per-step accent grid - Eight-pad sampler with grid, auto, and tap chopping, two switchable banks, three-band EQ, varispeed tuning - Project save, load, and WAV stem export with tempo map - Streams audio to any Mac DAW over USB (Inter-Device Audio & MIDI) - Sends MIDI clock over USB — Ableton, Logic, and Bitwig lock transport to the phone - Records stereo from any Core Audio interface (iRig, Focusrite, MOTU, and others) HOW IT WORKS Six faces. Perform pads on one, sampler on another, click and time signature on a third, projects on the back, I/O on top, master on the bottom. No menus, no tabs. Every control lives on the body. The click track is not a metronome. It is a three-voice drum machine with per-step accents, subdivisions from quarter notes to swing, and time signatures from 3/4 to 12/8. Set up a kick-snare-hat pattern, press record, loop on the beat. The sampler holds eight pads across two banks. Record from the mic or load from Files. Chop by grid, by transient, or by tapping markers. Each pad carries a three-band EQ, varispeed pitch, and an amplitude envelope. All eight play polyphonically. Recording quantizes to the bar, the beat, or runs free. A dedicated loop-adjust face trims each loop to the sample — drag the region brackets, snap to the grid, hear the result while the brackets move. Plug the phone into a Mac over USB. Audio Object appears as an audio input and MIDI clock source. The DAW locks transport to the phone's tempo. No drivers, no setup. Plug a USB audio interface into the phone. Audio Object names the device on screen and records through its preamps at up to 48 kHz stereo. WHAT IS NEXT A synthesizer — bass, chord, and lead modes — is in development for the next major release.

Verdict
The clearest difference is price: Audio Object at Free against Sound Maker Synth's $1.99. Audio Object also leads on rating (5.0 vs 1.0) and update cadence (every 2 months vs every 41 months). Sound Maker Synth's advantage is device support (3 vs 1) and iOS requirement (10.0 vs 17.0). On ratings volume, ads and in-app purchases there is nothing between them.
