DOES THE SD 2 OR THE SD 1000 HAVE THE ABILITY TO PROVIDE POWER TO A MIDI FOOT CONTROLLER  THROUGH THE 5 OR 7 PIN MIDI CABLE?

THANKS

JOHN

You have to try it....

I have never heard of any5/7 pin midi interface cable sending power only midi data?
jon

There is some power in midi out.
But some are not providing enough power.
Some hardware are using this MIDI power to avoid adding a power supply.

The midi buddy I just bought is supposed to be able to be powered through the midi din connection but I have not gotten it to work just yet.

Terry

The midi specification tells that midi out have a +5V in a pin.
But many midi devices give less than 5V.

Ah. I never knew there was enough power from a 5 pin midi for devices to work.
jon

Yes it is in the spec, and there are only two pins used even though it is a 5 pin plug . It works a little like phantom power on mics, albeit at FAR smaller voltages.

This paste is from the MASTERMIND GT midi foot controller manual.

The midi cable from the SD2 or SD1000 must be a six or 7 pin midi cable, and must be able to provide 12 volts DC or 9volts AC, and draw at least 2A of current. Then you can phantom power the Mastermind GT over the midi cable.

Actually the power supply that came with the GT is not very big and can plug sideways and take up just one space in a power strip. But I thought it would be nice if it was possible to phantom power it.

Thanks for all the input.

Terry, I'll check out you're MIDI BUDDY, How are you coming with the TRIPLE PLAY project?

Thanks,

John     



Remote In – This is a MIDI input port. It can be used for receiving MIDI patch data, program changes or can be used to connect multiple Mastermind GTs together and allow them to control each other. This is a 7-pin MIDI port, but you can always use a standard 5-pin MIDI cable to connect to this port.
MIDI Out – This is the main MIDI output. Connect this port to the MIDI device(s) you wish to control. You can use a standard 5-pin MIDI cable here, but if you connect a 7-pin MIDI cable, you can phantom power the Mastermind GT over the MIDI cable. If you phantom power, you can use the Mastermind GT without it needing its own power supply. Please refer to the note below for more details.
Accessory Power Out – These two power output ports provide 9VDC center negative power for powering tuners, wah pedals and the like. The outputs can deliver 100mA total. This is enough to power a typical wah pedal and any of the popular pedalboard tuners.
Power Inputs – This is the main power input for the Mastermind GT. The Mastermind GT requires a 12VDC supply with at least 2A of current capacity. NOTE: Do not connect power to this jack if you are phantom powering the Mastermind GT!
Remote In (XLR) – This is a second MIDI input port that works the same way as the other Remote In. This one has a 6- pin female XLR connector designed to connect to another Mastermind GT. Do not use the XLR and the standard DIN MIDI inputs at the same time! Doing so can cause unpredictable results.
MIDI Out (XLR) – This is a second MIDI output port that is wired in parallel with the other MIDI Out port. This one has a 6-pin male XLR connector designed to connect to RJM Music products such as the Effect Gizmo and Rack Gizmo, or another Mastermind GT. Do not use the XLR and the standard DIN MIDI outputs at the same time! Doing so can cause unpredictable results. This jack also accepts phantom power from a compatible device.
IMPORTANT NOTES ON PHANTOM POWER: Don't connect a power supply to the Mastermind GT if you are phantom powering it! Doing so can damage the Mastermind GT and/or connected devices! Also, before attempting to phantom power the Mastermind GT, please make sure the device you're connecting to is compatible. The device must provide 12 volts DC or 9 volts AC over pins 6 and 7 of the MIDI cable (or pins 1 and 2 of the 6-pin XLR connector), and must be able to handle the current draw of the Mastermind GT. Please visit our website for a list of devices known to be compatible.

John, I have been having great success when I can get things to work.  I have been working with Dan as I think I have to follow a certain process to bring the various USB items up otherwise I lock up.  I bought a powered USB hoping that maybe that would solve the problem but will not have a chance to work with it until this weekend. 

I need to do a little reading on the midi buddy and the powered situation to see if that would eliminate one more cord in the configuration.

Thanks,

Terry

Hi Terry, and Dan,

Have you looked at the imidiconnect2+ and the iconnectmidi4+?

You'd connect your laptop to the imidiconnect, which would also power the laptop, & I think it might take the place of the usb midi interface, your audio interface would also connect via usb & would pass through the imidiconnect, also the midi footcontroller would connect via usb. The 4+ also will accept an 8 usb hub. There's 2 midi in & out on the 2+, and 4 midi in & out on the 4+. Sweetwater is selling the 2+ for around $89.00.

Is this something that would help us Triple Players plug everything into and might help with maintaining the midi connection between the vArranger and Triple play and maybe latency issues?

I have just today got to the point where the vArranger is playing the styles with the Ketron voices, and the Triple Play is controlling the vArranger using the Triple Play software for the guitar patches and synths.

Before I could only use the Triple Play controller to play the Ketron voices with the guitar. Now I can hear the Triple Play Guitar Rig 5 patches on the guitar instead of the Ketron voices in the vArranger2.

Also I found out that the factory patches that you drag over to the USER patches, which number from 1-240, are the actual midi CC numbers as well as being the number of the user patch.

Thanks,

John

I think the usb cable only replaces the midi interface cable but the Sd1000 will still need external power supply as usb may not supply enough power to also power the Sd1000

jon

Hi Jon,

I never intended for the SD 1000 to be powered via the midi cable; But, the Mastermind foot controller to receive its power from a 6 or 7 pin midi cable from the SD1000 to the Mastermind.

But because of the enormous power draw of the Mastermind, 2Amps, it would have been too much even if the SD 1000 could have provided power through the midi cable.

Thanks,

John
