Laplace is a physical-modeling synthesizer based on resonator synthesis that makes it easy to create bowed string, plucked string, blown pipe and metallic sounds. But it is designed not to reproduce real acoustic instruments but to create new synthesizer sounds in different new ways.

Customer Reviews

Your ability to create new sounds unlike the factory set provided.

Film less Soundtracks

I love this app as well as all the apps created by this developer. Basically, the factory presets are just bad, but that can be a good thing. The first thing I look at before purchasing a synthesizer is can I create and store my original presets. On this inexpensive synth you can. It tests your ability to not have a ton of LFOs, Oscillators, Envelopes and it does make the sounds that are specified in the information paragraph easy. I like to take a synth known for some specific sounds and move as far as I can away from them. In one hour I had a half a dozen presets that were completely different from the factory set. If you want to challenge yourself, for $4.00, this synth is a great test for your creativity. 4 stars because no Bluetooth, other than that a lot to work at.

Exceeded my expectations


Not many synths in the iOS market can reproduce a wide range of natural sounds. Some of the better FM style synths can give good glass or metallic textures but for a long time that has been the limit. For a long time I have been falling back on the Sculpture Modeling Synth from Logic if i wanted a well-wrought wood or nylon synth sound and not just some sampled instrument. No more. I have grown quite comfortable wrapped up in a patchwork quilt of apps and get cranky when I have to use the computer for anything other than recording and mastering. Thank you, Laplace. And please don't introduce any IAPs in the future. If Korg cannot do this tastefully then no one can.

Unexpectedly versatile


I love physical modeling synthesis!! Laplace (pronounced: la-PLAHZ) is terrific.

The design is very clever and effective. It is both easy to get started and relatively easy to get a HUGE range of sounds from breathy flutes, mellow bowed sounds, to brass ensembles. It is pretty intuitive once you figure out the 3 different mixer knobs— those help you hear what each little element is doing.

I wish the reverb was a little nicer. I also wish there were a couple more parameters that could be controlled by velocity. Notwithstanding, this is a unique and delicious synth!! Kudos to iceWorks!!!
