DXi FM synthesizer App Reviews

Sounds cool but is useless to me until then

Nice sound, fun to program. A few more sample patches would be nice, but I have already programmed about 10 more in less than an hour. Anyone looking for a nice sounding FM synth will be pleased.

Good sounding , easy to use . can run in lofi mode for that extra authentic late 80s coldness ;) 4 out of five .... 1 more star for : making the seq section not a pop out , but maybe a page instead ie; instead of seeing env section ? Update the filter with a more robust sound ? Allow user to specify what the mod wheel does !

This reminds me of my old Yamaha DX-11, but for a much better price. Very nice!

I was 16 and saw my first DX7. That was the synth that got me hooked. This is a great homage to those days of synthesizers. Faithfully replicated in virtual form, and sounds quite good. A lots changed since those days but the classic sounds this generates are a very welcome addition to the iOS synth market. Any synth lover should appreciate this. Its a no brainer, just click buy.

Love the Sound of this synth and the extra voices in the latest update. 5 Star app all day. A Must have in your synth arsenal. Dont Sleep. Thank You for this excellent app!

Does the job well. Needs Synthstation support and more sounds and downloadable sound libraries. Then 5 Stars.

Sounds just like the old days!

Love. This. App.

Dont waste your precious time exploring presets - explore the capabilities of the synth instead: Its magical. BUT... It would *greatly* benefit by better midi support (imagine this with virtual midi and midi learn capabilities!!!) Also, less critical, but a couple more panels of FX would take this to a whole new level.

This synth sounds amazing!!!!! Theres something about the sound that keeps its vintage identity totally intact while still perfectly inspiring new ideas and fitting in with any modern sound youre looking at creating!!!!!! Thanks for this synth!!!!! Please keep on developing great instruments!!!!!!

This is promising app which emulates a 4-operator (aka four oscillator, but in FM you usually use at least one oscillator as a modulator) FM synthesizer like the DX-100 or TX-81Z. The sound is nice and it has a nice set of Yamaha-style algorithms (i.e. ways of wiring up your carrier and modulator oscillators), and a variety of waveforms (i.e. more than must sine waves) give you additional flexibility. Effects include a basic delay/chorus and fixed lowpass filter which can be used to cut some FM grunge for soft sounds. Audio cut and paste and a simple step sequencer are also nice. Unfortunately, the app is just not very usable because the sound keeps dropping out! Please keep working on it, because I would love to have a nice FM synth on the iPad!!

FM synthesis is a powerful tool which allows for the creation of lush, harmonically rich sounds with a very small set of oscillators. Unfortunately, compared with additive or subtractive synthesis, its relatively impenetrable - a problem that was made much worse by the menu diving GUI in the Yamaha DX series synths. This app does a great job of creating a GUI that clearly explains the structure of the sound and what the parameters do, making FM synthesis fun for the first time Ive ever experienced. There are a bunch of good little synths for the iPad, and a lot more bad ones, but this is one of the best available. To the dev, please make a pro version of this synth with midi input, and over sampling so the higher harmonics dont alias back down. I would buy it all over again.

Big sound. Easy to program.

This is a crystal clear sounding 4 operator FM synth, a baby brother to the classic 6 operator Yamaha DX-7 synth. These FM synths have a distinct sound, which is very different than the typical subtractive or sample-based synth. The DXi implementation sounds great and the UI is great, especially on the iPad. The algorithm/operator editor is cool, swiping through the algorithms and then touching an operator to configure it. But to me the most fantastic part is the ADSR envelope editor, which, on iPad, highlights each stage over time as a note is played...on the one hand, its completely obvious, but Ive seen a lot of synths and never encountered it before. If Mr. Mizuhiki came up with this, he deserves some kind of prize, and hopefully he didnt patent it!

While playing the DXi, the pages on my iPad flip, making it impossible or at least difficult to play live. Please look into this. Otherwise, its a decent synth for the price. OK, I was wrong. I had my multitasking switch on. Problem solved.

Recently I went completely mobile in my production, both to say that I did and also because the workflow in BeatMaker2 is so intuative (spelling error and pun intended). The sampler synth in BeatMaker 2 is incredibly lacking, with amateurish sounding melodies littering my projects. Before I tried mobile synthesizers, I found myself creating melodies in Ableton or Reason then exporting them as WAVs to BM2. I wanted a centralized production environment, trying many mobile synths on the App Store, including Addictive Synth, Animoog, and other classics. While they are good pieces of software, none stack up against DXi for my own sound. The ease of use when manipulating patches is unmatched. Different algorithms to test out on your synths? This app is like Abletons Operator plugin, but mobile! With the included AudioCopy tool, I love and now rely on this software. However, all I ask: • Be able to hold/tie/slur/accent notes in the sequencer. • Be able to save sequencer arrangements. • Be able to export sequencer arrangements as MIDI/audio. While I am aware that you are able to hit "record" then "play" on the sequencer (as I have been doing), this would be much cleaner. These are minor requests that only pertain to assisting my own workflow. This synth is a must-have for the mobile producer. Squelching bass, buzzing leads, beautiful pads, and evolving textures... All possible with this $2 synth. I wouldve paid $20 with a fully fledged sequencer part (see my list above). 5/5.

I did not like this synth at first. However, I tried it again after a while last night after setting up rtpmidi and using core midi and a keyboard midi controller to control this synth. WOW, I was able to make some sweet bass! I tried to get the same sounds in-app but I just couldnt. My midi keyboard will allow me to go four octaves lower than the in app keyboard does and that has made all the difference for me. I would suggest a future update to increase the range of the in-app keyboard. I see this synth supports midi CC for cutoff and resonance, but it would be cool if maybe it were possible to midi-learn other parameters. (it might be interesting to say, use a sequencer to change waveforms or to LFO the ratio, etc., this is my first real experience with FM so I dont know).

The last two times I used this app, the display zoomed in by itself, and even when I closed the app, the display would not go back to normal without a hard reset. Im afraid there might be a virus (dont take my word for it, I dont know for sure!)

I just sold my dx7 and have been missing it. :( and while this app couldnt replace it, it has been really handy in its abscence. The only thing more I could ask for would be for more control over the LFO. I love the sound when the mod wheel is just a little up but I could sure use some control over wave shape, speed, and depth to get some really dynamic FM patches.
