Roland Promars Plug Out

I think this one sounds a lot better than the System 1 original! Roland is going to be king of digital synthesis again.

Namm 2015 Roundup: Roland JD Xi, JD XA, Dave Smith Prophet 6

Roland JD Xi

This one looks pretty good, except for the small keys (you can play triplets, but still my hands are too big for it). Its pretty much an analog / digital, all-in-one, groove keyboard. I haven't seen a demo from the digital side except that it has supersaw. I really hope these voice well and combine the oscillators in a patch. But whats even better is the Roland JD-XA!

If you are into keyboards, this is obviously the one you will want to wait for.

What else?


It sounds great again and is packed with features! It looks like a revisit to the Prophet 5.  Its really good looking! Listen to it here on soundcloud. I like it when these companies are fully ready to show everything off.

Where is Yamaha? I don't know yet...

So far I think these are the best products to post up. Korg has some nice new replicas, and there are some other analog monophonics, but those are not things I'm into...the tech is just too old! I need patch memory.

Akai Pro Advance 25,49,61 Keyboard Midi Controllers come with software.

New Midi controllers from Akai. They have a built in screen of some type and come with some software instruments. They do look pretty cool if you work inside the computer. I'm really afraid of midi controllers. The ones promising to be ultra integrated have been the hardest to set up. Time will tell.

Jupiter 8 sounds on the V-synth

Lets synthesize the Jupiter 8 sound!

The trick to making a Jupiter 8 on the V-synth is different from other analog types. Its quite easy to make a Moog lead (or analog pad) on the V-synth by just using the TB-303 filter. I don't have a JP-8 in front of me, but the pitch seems to be quite stable.

Use a small randomization and drift factor for pitch.
 -2, RND PITCH LFO, -2 Randomization in the pitch section.
 The above setting will make it go out of tune by only 4 cents!  Other analog instruments use more.

The PWM can be drifted by -30! If you use a basic wave, like triangle or SIN, you will start to get the right shape, but don't go too bright. You can also adjust the attack and envelope if you want.

Next use a regular -12db filter, with really moderate settings! I thought the filter would need special programming beyond the what V-synth does, but thats not the case. However, the resonance is quite impossible to nail down perfectly. The attack and decay depend on the sound you are making. I actually think less than 5 attack is not necessary.

Amplification is the final part.

Use the Guitar amp MFX, JC-120 amp. Does this amp have the same circuitry as the JP8? I don't know, but maybe it was used on a lot of records and it gets the tone right. Turn the gain to LOW. Set the input to 43 or so. Turn off the speaker. Set the EQ Bass and Mid to 110, treble turned down a bit. Brightness off. You might have to nudge things around to get the proper brightness. This amp kind of makes the treble sing and thats why we use it.

This isn't a complete tutorial to a specific sound, but now you have the basics. There are not a lot of options to get a modeled analog sound on this keyboard, but there are tons of workarounds and secrets!

Using Feedback in Sound Design

One way to make a sound more alive is by using feedback loops at different stages. In a synthesizer or FX chain a loop will shape sound with a repeated frequency. The sound is referencing its own signal from another part of the system. Ultimately the sound will hit a maximum resonant frequency or amplitude. If the system is well designed, it won't blow your speakers! If its digital, the worst that can happen is clipping. You can adjust levels to create the most interesting effect without going overboard. There are ways to control the sound so its not just a constant overload which I also mention below.
  1. Feedback Knobs - This is found on chorus, phasers, delay etc.
  2. Dynamic Envelopes - Like a compressor, or dynamic filter, these reference the amplitude of the input to make the sound come alive. Found on V-synth, lots of software FX filters.
  3. Feedback Oscillator or Loop chain built into a synth - This is found on Dave Smith's designs and also V-synth. This can create circuit overload and clipping sounds.
  4. Reverb - Reverbs are a type of feedback. The sound is repeated back to you and affected by time / resonance.
Step Two: How to control and shape the feedback.

Try amplitude modulation or randomization before the inputs. The goal is to find some kind of balance and interesting use of the feedback. The end result is a new sound with some cool time effects. All of the modulation and self referencing will make the sound come alive.

WARNING, this is what happens when you feedback a Roland supersaw wave.

Roland JD-Xi Leaks

It looks like it has mini keys and a small mod wheel. It likely has a step sequencer with the bottom pads. I'd imagine the quality is similar to the midi keyboards, which is acceptable, but not amazing key action. Hopefully this has on-board sounds. I'd imagine this connects to downloadable AIRA / presets. The fact they are using the JD letters probably means it is synth + some of the original roland waves, but not Supernatural. Thats my best guess. I'm also going to guess this costs $599 or less.

Waiting for NAMM 2015

Lately I'm waiting for NAMM 2015 announcements. I'm looking forward to keyboard workstations and audio interfaces. Both areas really aren't developed for pro-sumer anymore. Audio interfaces tend to be overpriced with too many connection types and stability problems. Keyboard workstations tend to have gotten cheaper and have worse builds than before. If Roland does not announce a real workstation I think I'll be giving up on their company entirely. If you spend $1000 dollars you don't deserve a plastic toy. I won't wait anymore after 2015 NAMM. Hopefully exciting stuff leaks out.
