ARP 2500 - The Lost Modules

[@ranzee]

Excellent news!! A very fascinating look at the amazing ARP 2500 synthesizer and all of it's potential expansion ideas. We are very lucky to have you recreating these modules for us - and I can't wait to get my hands on them! Bravo!

[@TheMachinesWon]

Fills my heart with joy to be able to add these to our set ups! Thank you for your hard work and passion on the 2500 series 🙌🏼🙏🏽

Fantastic work. This is very exciting to see more manufacturers making 2500 modules. A great supplement to the Behringer line. Thanks so much. Cheers

[@amsynths]

Many thanks, much appreciated! When working on the Behringer 2500 project I did discuss the potential for additional “lost modules” but we were not sure of the market and I had less information to go on. Now its time to do them!

[@moogfooger]

@@amsynths Wonderful. I have the whole 2500 series right now and look forward to breathing some new life into it. All your hard work is fabulous. Cheers

I like that Cherry Audio incorporated a few of these in their software emulation for Voltage Modular. Your page has always been such a great resource for this stuff .

[@amsynths]

Cherry Audio have done a great job, 1019, 1026 and 1042 with overdrive on the VCAs. The vertical design for the 1042 is likely to be accurate to the original, but hard to fit in eurorack. Hope the video inspires more modules from Cherry!

Beautiful video. Thank you so much!❤❤

Dennis was actually fired by Alan for refusing fixing contacts on returned string machines he during design had warned Alan would fail. Now both are dead and all their anger and animosity is fading into the sun like the dust of angels. Burns quite well, like gasoline into a BBQ!

[@amsynths]

Ah that explains it! Many thanks for the insight..

It's great to see this happening, thank you.

Good luck sir, awesome job!

Love this video!!!

[@NickHchaos]

Great stuff. Still says “out of stock” on your shop for these? AJH has a noisilator!

[@amsynths]

The 1035 and 1040 modules will drop next week. The other 4 will drop during May - July. There are also some additional surprises planned; for example the 1004P expansion module for the B1004 to provide indiviual waveform mixing.

[@NickHchaos]

Ah, so be awhile still for that filter then!@@amsynths

[@amsynths]

The 1031 prototype is sounding good, next stage is production pcbs and panel. However it is 6-8 weeks away, so that it can be launched with exciting new control knobs that are being manufactured in the USA. There will be more filters added in the summer in the 2500 style, diode, resonantors, vintage ladder.

[@NickHchaos]

@@amsynths How would you compare the 1031 sound and topology to something like a SEM filter?

[@amsynths]

@@NickHchaos The 1031 has voltage controlled resonance and a more complex damping cicruit than the SEM. Neither self oscillate by themselves, but by adding a CV into the 1031 QCV input and putting resonance at max, it will break into self oscillation. The 1031 has trimmers to adjust the Q behaviour in LP and HP modes and faster Op Amps . The more complex damping gives a smoother sound as Q is increased. I do have a SEM here, so I will try and video a comparison (along with a B1047).

Bring them on all of them

looks good
