this is the first Synthino post.

Some details for the archives:

"Synthino is a fun collaboration project started in 2014 between two Minneapolis based DIY kit makers and members of TC Maker a non-profit Minnesota based organization focused on growing the maker community.

Electronics maker nootropic design has pushed the boundaries of Arduino based electronic devices by incorporating unique integrated circuits (ICs) in Arduino compatible shields for everyone to be able to enjoy without racking their brain over datasheets or dealing with nuances of circuit board layout and design. While taking special pride in the documentation, development, and testing virtually all nootropic design kits are suitable for hobby, professional, industrial, and even government applications.

GetLoFi offers information and kits for musicians and first-time solderers who are not opposed to modifying their gear through a process called "Circuit Bending" or building from scratch a variety of analog circuit noise makers. Bringing to the table a musician's perspective GetLoFi team helped to develop essential hardware and software features of Synthino...

"For sale is one future retro 777 acid synthesizer. It is very rare, as only 777 were ever produced, and is special in that it is not a 303 clone (though it can do the 303 thang very well) but rather it's own acid synth that can go WAY above and beyond the capabilities of even a devilfish 303. The modulation capabilities are immense, and it has midi & CV in/out built in (it can be used as a step sequencer for other gear.)"

eBay Hacked - Change Your Passwords!

"SAN JOSE, Calif.--(BUSINESS WIRE)--eBay Inc. (Nasdaq: EBAY) said beginning later today it will be asking eBay users to change their passwords because of a cyberattack that compromised a database containing encrypted passwords and other non-financial data. After conducting extensive tests on its networks, the company said it has no evidence of the compromise resulting in unauthorized activity for eBay users, and no evidence of any unauthorized access to financial or credit card information, which is stored separately in encrypted formats. However, changing passwords is a best practice and will help enhance security for eBay users.

Information security and customer data protection are of paramount importance to eBay Inc., and eBay regrets any inconvenience or concern that this password reset may cause our customers. We know our customers trust us with their information, and we take seriously our commitment to maintaining a safe, secure and trusted global marketplace.

Cyberattackers compromised a small number of employee log-in credentials, allowing unauthorized access to eBay's corporate network, the company said. Working with law enforcement and leading security experts, the company is aggressively investigating the matter and applying the best forensics tools and practices to protect customers.

The database, which was compromised between late February and early March, included eBay customers’ name, encrypted password, email address, physical address, phone number and date of birth. However, the database did not contain financial information or other confidential personal information. The company said that the compromised employee log-in credentials were first detected about two weeks ago. Extensive forensics subsequently identified the compromised eBay database, resulting in the company’s announcement today.

The company said it has seen no indication of increased fraudulent account activity on eBay. The company also said it has no evidence of unauthorized access or compromises to personal or financial information for PayPal users. PayPal data is stored separately on a secure network, and all PayPal financial information is encrypted.

Beginning later today, eBay users will be notified via email, site communications and other marketing channels to change their password. In addition to asking users to change their eBay password, the company said it also is encouraging any eBay user who utilized the same password on other sites to change those passwords, too. The same password should never be used across multiple sites or accounts."

" 201e - 4-panel Powered Boat w. upgraded 24-space PSU (rack ears included)

206e - Mixer/Preset Manager w. rear panel 1/4" output expansion
A six input, two output mixer with controls for level and stereo location. Two of the locations can be voltage controlled; the remaining four can be continuously panned.

A preset manager is also incorporated as well as dual 1/4" rear panel output.

261e - Complex Waveform Generator
The Model 261e Complex Waveform Generator features voltage-controlled modulation of pitch, amplitude, and timbre, and a multi-dimensional, voltage-controlled timbre space. All of the 261e's timbre processing is performed by analog circuitry, thus eliminating the aliasing that can be introduced by waveshape table driven systems.

A separate modulation oscillator can be synchronized to the principal oscillator or to note-on MIDI messages. Its waveshape is voltage controllable, and can be continuously varied from sine to pulse. The modulation oscillator can track the pitch of the principal oscillator with variable offset.

In conjunction with the model 225e MIDI Manager, the 261e's pitches respond to internally routed MIDI messages. Up to four 261's can peacefully co-exist in a single system, each with its private MIDI channel.

As in all 200e series modules, the settings of the 261e's pots and switches can be memorized as a part of a preset configuration.

266e - Source of Uncertainty
The Model 266e Source of Uncertainty is a general source of musical unpredictability. Divided into 4 sections, each section serves a unique function.

Noise comes in three flavors. White noise is electrically flat, but acoustically balanced toward the high end of the spectrum (+3 db/octave). Integrated white noise has a low spectral bias (-3 db/octave). Musically flat noise has a flat spectrum (constant energy per octave) and is a particularly useful source for subsequent processing.

Fluctuating Random Voltages are continuously variable, with voltage control of bandwidth over the range of .05 to 50 Hz, making possible changes that vary from barely perceptible movement to rapid fluctuation.

Quantized Random Voltages change on receipt of pulses. Their number of states is voltage controllable from two to twenty-four, and their distribution can be varied both spatially and temporally.

Stored Random Voltages have three parameters under voltage control. Degree varies the amount of randomness; chaos alters the distribution from just a little uncertain to total chaos; while skew biases the randomness toward one extreme or the other.

All settings of the 266 may be stored and recalled under control of the model 206e preset manager.

291e - Triple Morphing Filter
The 291e Triple Morphing Filter consists of three voltage controlled filters operating independently or in parallel.

The amplitude, center frequency, and bandwidth of each filter may be independently voltage controlled. Each may be modulated with externally applied signals.

The morphing capability might be described as moving through a series of snapshots of the filter, with each snapshot consisting of a complete description of the filter parameters, and with each parameter continuously varying between snapshots. Morphing is accomplished with an applied voltage, or alternatively can be initiated with a pulse, with each stage time independently set. Up to eight stages may be employed.

A solo switch provides editing convenience, and an expand input allows ready expansion of the filter.

All of the 291e's settings may be stored and retrieved with the model 206e preset manager"

Buchla 285e Frequency Shifter / Balanced Modulator

"This module is the e series reincarnation of the 285. A long time coming, but well worth the wait.

The top section performs frequency shifting; up and down outputs are simultaneously available. The reference frequency can be externally applied or internally generated; the latter can be voltage controlled and f.m. modulated.

The bottom section is independent, and functions as a balanced modulator of applied signals. The degree of modulation is voltage controlled, and the reference frequency can be internally generated or externally applied, as in the frequency shifter. A separate output is dedicated to classic ring modulation, a subset of balanced modulation.

All settings of the 285e can be stored and retrieved with the 225e or the 206e preset manager."

via the seller: "looks like the previous owner disfigured top of this TQ5, maybe trying to clean it with an acetone based cleaner. so to clean it up I had to sand and repaint the partial face w/ a silver/grey "hammered on" textured paint. it looks pretty cool and a lot better that it did. and while I was inside,i removed dead battery & I soldered in a new battery holder w/ replaceable 2032 battery, i did a factory reset & set day & time, item works great & sounds fantastic!"

"The TQ5 was an entry level FM Workstation in a keyboardless, sparsely decorated desktop unit. It takes after the smaller line of FM synthesizers like the DX-100, DX-21, DX-11, TX81Z, and FB-01. These featured 4 FM operators per voice, and 8 voices of polyphony. And like the latter three, 8-parts multitimbrality was featured. The TQ5 also had easy "Quick Edit" keys to access some basic parameters for instant tweaks. The TQ5 was capable of many of the good, the bad & the weird sounds FM synthesizers made.

The TQ5 featured built-in digital effects and an 8-track sequencer (with 8 song capacity) rounding out the "workstation" aspect of this machine. Designed for use as a stand-alone FM workstation or as a MIDI module, the TQ5 was poised to bring high-end FM sounds to entry-level users."
