Tom Oberheim & Dave Smith OB6

[idylmind]

I had trouble for a while as well. Use the boot loader mode on the OB-6. Hold the WRITE button while powering one. That solved it for me.

[udenjoe]

OK, this will need the MIDI cable. I’ll figure it out.

[idylmind]

Correct, you’ll need a third party usb midi device.

[jefferymac]

@udenjoe

That didn’t work. I even changed computers, new download using sysex explorer. When I load it, it will countdown to zero and just reboot. No loading phase happens as described.

Make sure you are on latest OS as well—apparently the upgrade doesn’t work so hot from 1.5.5.

[Kenneth]

so this is better
check this easter egg
first I thought it was a joke but it seems NOT

The slap has to be not to soft but also not to hard to work

didn’t tried it yet on my ob6

Surprise! OB-6 Easter Egg Reveal With J3PO

[udenjoe]

I think this is my problem. Any idea where I can get 1.5.8? Or any non 1.5.5?
I’ve tried everything and I’ve been updating synths for 20 years. I’ve never had this problem before.
I’m waiting on a response from Sequential as well.
Thank you for your helps!

There are a lot of options discussed in the Sequential Thread for this mod: Vintage Knob for OB-6?

That is where I would go for community support on this particular issue.

[chiasticon]

my update was a little funky as well… it counted down from 999, then rebooted, then the lower effects display counted down (I think from 6 to 1) and the main display was blank. nothing further happened. I was scared to re-boot so I left it like that for about ten minutes, then rebooted. it lists the new OS number and the Vintage Mode seems to be working right (in that it sounds awesome, and distinctly different from slop mode).

I used Sysex Librarian over USB from a Mac, fwiw. and I was on a pretty old OS. I want to say it was 1.5.4 but I’m not certain. I’ve never updated it since I got it in early 2018.

[Michael_S]

Is one of you controlling the OB6 via MIDI CC/NRPN?

I’m currently sequencing the OB6 via the Digitone which works fine for notes and velocities, yet I can’t figure out how setup the control message for more specific stuff (e.g., pulse width)

[PeterHanes]

@Michael_S

I’m currently sequencing the OB6 via the Digitone which works fine for notes and velocities, yet I can’t figure out how setup the control message for more specific stuff (e.g., pulse width)

The OB-6 manual includes a table of received CC messages for sound controls. In it, for example, the CC numbers for VCO1 Pulse Width and VCO2 Pulse Width are 71 and 79 respectively.

For the OB-6 to receive those messages, you need to set Param Rcv to “CC” in the OB-6’s global settings.

[Kenneth]

yep I’m
I just look at the manual which cc number the parameter off the ob6 has who I want to control
and then I choose one off the encoders on the AMP page and select that cc number

Synthpunk has the not-entirely-crazy idea that Dave Smith will come out with a new OB-Xa in the next two years. The idea is based on (aside from Behringer) Korg’s success with re-issues plus the new Prophets. Since this is about getting a dream synth and not filling a needed slot, I figure I’ll forget about it once again, and if this aspirational Xa pops up in the next few years, jump on that. I expect such a thing would be $4-5k—if we’re lucky—so might as well not overspend now, I reckon. Aside from the greater timbrality and voice count, is there anyone who considers the X’s sound to be close enough to the Xa that the difference doesn’t matter? Even so, there’s the greater timbrality and voice count.

Is An Oberheim OB-X Reissue Coming From Sequential?

“It’s not often that you get to revisit your past, retrieve some of its magic, and give it new life….”

It seems Synthpunk’s prediction was almost spot on. I’m pretty much in on this even with Sequential’s narrow implementation of MPE. I’m glad I didn’t jump the gun.

[korpinen]

This is still mere prediction and speculation though, isn’t it? Especially this soon after the upgrade to OB-6, wouldn’t an OB-X feel a bit like Sequential cannibalising their own OB-6? Don’t get me wrong, I think it’d be wonderful and like I mentioned above, I’m destined to get another SEM poly at some point.

[lelluds]

It is but I suppose with enough interest - which there seems to be from peoples response to the rumor - it might just happen. Although maybe he just wanted the name. But with the p5/p10 in mind it’s not as unlikely at least.

About it competing with ob6, they’re two different beasts in different price ranges and sequential still offers the p6. But it’s a valid point, and my guess is that this one is a bit more niched compared to the p5.

[HoldMyBeer]

I would think the timing is about right. The P6 came out in 2015, and then the following year the OB-6 came out. And I feel they are following the same path. The P5 came out a few months ago, so sometime this year, the OB-X should come out.

The firmware update to the OB-6, the use of “vintage mode” instead of “slop”, is the same update for the P6, and the same feature that was on the P5 at release. My guess is that it will be a standard feature on Dave Smith synths from here on out.

[Nils]

Vintage knob sounds absolutely fantastic. A siginificant improvement to the OB-6!

[johnl]

And it’s out now: Sequential

Sequential has just released a new OS for the Prophet-6 and the OB-6 that adds much-anticipated features:

• Support for MPE (MIDI Polyphonic Expression). This enables the Prophet-6 and OB-6 to respond to MPE-driven controllers such as the LinnStrument®, Expressive E Osmose®, Roli Seaboard® series, and others.
• Prophet-5 Rev 4-style “vintage” mode. This gives the Prophet-6 and OB-6 a looser, more organic sound that emulates the behavior of vintage synthesizers where the behavior of individual oscillators, filters, and envelopes vary from voice to voice.
• Improved aftertouch curves for enhanced expressiveness when using the Prophet-6 and OB-6’s own keyboard.

“A technical overview of the Vintage Knob implementation in new Sequential Prophet 6, OB-6, and Prophet 5 Rev 4. I spent several hours analyzing the Oscillators, Envelope ADR timings, and Filter characteristics.
This video explores the vintage knob behavior in depth, and also offers up some recommendations on how adjusting the values could greatly improve the usability of the Vintage Knob across a range of values.”

Vintage Knob Analysis and Recommendations - Prophet 6

[tomfs]

The first thing I noticed when starting to play with it was that with max Pan Spread, and max Vintage, one side became way brighter than the other, so the stereo balance was really strange.

I assume this is because the Pan Spread always spreads the same voices to the same place, so going off the video, Voice 6 must always be right on the same edge of the stereo field. Would be nice if the most extreme variances on the voices were at least balanced across the stereo field.

[aortan]

Is it possible to program sequences using only the desktop module?
Can you have the arp play by itself?

Or do you need a controller to make any kind of sound?
