@ LED-man
When is the estimated order date for the MP7 ?
I expect about 5-6 weeks after today.

I have to update the schematics with the modifs applied to the MiniP7.
Find a work-around to the switched jacks, or use a switched non-Lumberg version.
Route the PCB. Order a trial and debug it.
Then another 2 weeks for the subcontractor to provide their quote.
Fortunately, I do not have to re-investigate transport, so that part will go swifter.

@ Dr Gris and all other having problems with my pdf

please feel free to print the order form and fill it out by handwriting.
Just scan or take a 'clear' picture and return by PM to me.

Sorry for all inconveniences it may have caused.

B rgds,
Boogie

Orders are arriving.

For me, it's an appreciation for my work.

Thank you !

Boogie.

Why no option for PCB plus panel only, without through hole components?

(I ordered the through hole components when the BOM was released)

hello all,

before putting the kits and prices online I did a balancing of the prices and the kits.
8 MW's were invited to provide feedback.
Kit combinations were not really discussed in that balancing.
I'll keep that in mind for the MP7 kit combinations.

Nevertheless,
I wouldn't be Boogie if I didn't show any flexibility.

I've attached a new order form with this option.
The full BOM inclusive slider knobs is also in this document.

Boogie.

PS
It will be difficult to please every-one's needs or preferences, so please accept the provided combinations as they now are, Order Form V3. (Order Form V2.1 is also still accepted, as well as all orders placed already)

hello all,

this post to let you know I started working again on the MP7 'fully loaded' version.
Current status is:
all components on PCB
next is to fine tune component placement
route the board
ask for prices
in the mean time run prototyping
debug
etc...
I'll keep updating about the progress.

Fully loaded, what does it mean ?
The same sequencer as in the MiniP7
All of the Minipops7 instruments.
Inputs for
Clock In
Sync In
Midi In
Trigger for each instrument. (levels 5 V to 18V)
All inputs with basic ESD protection by a 100pF cap.

Outputs
Clock Out
Sync Out
Trigger out for each instrument (selectable 5V or 12V)
Main Audio out.
Individual instrument outputs (Mono jack necessary)
Automatic rerouting of output signal to respective jack interrupting the audio from that instrument to the Main Output.
All outputs with basic ESD protection by a 100pF cap.

All of the above on 1 PCB, no additional module for triggers needed anymore.

The specs for the MiniP7 look good! :tu:

Could you explain the difference between Clock and Sync signals please?
I assume the former is a 4PPQ signal whereas Sync is like Sync24 or Sync48, is that right?

The render of the MiniP7 prototype PCB has fewer inputs and outputs than listed in the specs.
Do some of the I/O share sockets?
Does insterting an external trigger for an instrument override the internal sequencer?
You mentioned some potential grounding-related problems before regarding the use of certain sockets;
did you find a particular socket that worked for your application or did you find a workaround?

Nice to see you again.
The specs for the MiniP7 look good!
Is it possible you refer to the specs of the MP7 ? not MiniP7 ?
The previous screendump is the MP7.
I assume the former is a 4PPQ signal whereas Sync is like Sync24 or Sync48, is that right?
CLK is 1 puls per 16th note or 12th note (16 or 12 counts in a measure)
SYNC resets the Rhythm beat counter back to 0, this can be assynchronous.
Both occurences at the same time will reset the measure back to the beginning and play the first 16th of the measure (the first 16th note of beat 1)
Do some of the I/O share sockets?
Yes, All Trigger In are on the Tip, Trigger Out are on the first Ring.
Same for the CLock and Sync.
Does insterting an external trigger for an instrument override the internal sequencer?
No, the internal Sequencer stays connected. The external Trigger is ORed with the internal trigger.
Image
The components in between the Jacks are level shifters and Diode OR gates.
This means that one needs stereo plugs for the trigger In and Out. Which now makes me realise that I have to foresee a short circuit protection on the outputs.
You mentioned some potential grounding-related problems before regarding the use of certain sockets;
did you find a particular socket that worked for your application or did you find a workaround?
It's all done with work arounds. This also has te advantage that the output levels can be different (higher) then the internal signals going to the final preamp.
Image
These components are added compared to the initial render of the MP7 and provide selecting audio at the respective jack while at the same time supressing that instrument to the main output.
The ring of the Jack is used as a switch with the GND of the plug. Thus using a mono plug for the audio is a necessity.

Splitting the thread

Post by Boogie » Fri Apr 06, 2018 8:45 am

Hello all,

to avoid mixup of MiniP7 and MP7 I decided tot split this thread in two seperate threads.

For the MiniP7 clone, pls continue here:
viewtopic.php?t=199360

For the MP7 'fully loaded' version, pls continue here:
viewtopic.php?t=199361

B rgds,
Boogie.

Hi Boogie,

I was some time off, bit is it still possible to order the MiniP7 ?
It really would to be a fantastic add-on to my synth collection.

:yay:

And sorry for asking, but is there any chance to add a (3rd party) basic Midi-interface (as the Mini-implant) on your MiniP7?

Thanks.

hey Fitchie

you're at the wrong thread here.
I split this one into the MiniP7 and the MP7 some weeks ago.
Pls visit the MiniP7 thread to follow the status of the MiniP7:
viewtopic.php?t=199360

I will no longer actively update this thread.
